When creating a right triangle using 3 squares as seen in the online video, which sides create the right angle in the triangle?
When creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle (see image attached below).
Creating a Right Triangle with Three SquaresThe right angle of a right triangle is formed by the two small legs of the right triangle that are perpendicular to each other.
Just like in the diagram attached below, the two squares with the smallest sides will form the right angle in the right triangle.
Therefore, we can conclude that when creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle.

find the common difference for -31,-26,-21,-16
Answer:
The common differences is 5
Step-by-step explanation:
The difference is 5. Why? Because 5 is added to each term to arrive at the next term. so ... the difference a2 - a1 = 5.
E.g. -31 + 5 = -26
Ava, Lucas, and Maria are playing a game where they pass a pull-back toy to one another in a path that forms a right triangle. Ava sends the toy to Lucas. Then, Lucas sends the toy to Maria. Finally, Maria sends it back to Ava. The angle formed at Lucas' position measures 90° and the angle formed at Ava's position measures 40°. The distance from Ava to Lucas is 12 feet.
Ava is trying to determine the other measures of the triangle created by the toy's path. Give each distance in feet rounded to the nearest tenths place.
The distance from Maria to Ava is ___ feet.
The distance from Lucas to Maria is ___ feet.
The angle formed at Maria's position measures ___ degrees.
Using relations in a right triangle, it is found that
The distance from Maria to Ava is 15.66 feet.The distance from Lucas to Maria is 10.07 feet.The angle formed at Maria's position measures 50 degrees.What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, the situation is modeled by the graph given.
First, we have to remember that the sum of the internal angles of a triangle is of 180º, hence:
The angle formed at Maria's position measures 50 degrees.
Then, for the distance from Maria to Ava, which is the hypotenuse:
[tex]\sin{50^\circ} = \frac{12}{h}[/tex]
[tex]h = \frac{12}{\sin{50^\circ}}[/tex]
[tex]h = 15.66[/tex]
Hence:
The distance from Maria to Ava is 15.66 feet.
Finally, for the distance from Lucas to Maria:
[tex]\sin{40^{\circ}} = \frac{d}{15.66}[/tex]
[tex]d = 15.66\sin{40^{\circ}} = 10.07[/tex]
The distance from Lucas to Maria is 10.07 feet.

Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.
y = 9x
Part A: How many more dollars is the price of a box of Luke's original brand of cereal than the price of a box of the super-saving brand? Show your work.
Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work. (10 points)
Answer:
See below.
Step-by-step explanation:
Part A
"y = 11x is the function for the original boxes that he bought...it was $11 per box.
y = 9x is the function for the super saving brand...it is $9 per box
so there is a $2 difference between the original and the super saver."
Part B
"original box.....6 cereals
y = 11(6)
y = 66
super saver....6 cereals
y = 9(6)
y = 54
66 - 54 = 12.....so Luke saves $12 per month by buying the super saver brand."

Levi determined that y=2 is NOT a linear function because it does not take the form y=mx+b.
How would you explain why Levi's reasoning is incorrect?
Step-by-step explanation:
y=2 is just y = 0x + 2 so basically m=0 and b=2
The given line has a slope of 0 and y-intercept form and levi's reasoning is not correct.
What is the slope-intercept form of a line?The slope-intercept form of a line is represented by y=mx+c where m=slope and c is the y-intercept of the line
Given here: The line y=2
Now y=2 can be rewritten as y=0.x+2
which can be interpreted as a line with slope=0 or the line is parallel to x-axis and has its y-intercept at y=2
Thus the equation was rewritten in slope intercept form and thus is a linear equation.
Hence, The given line has a slope of 0 and y-intercept form and levi's reasoning is not correct.

√(-√(3)+√(3+8√(7+4√(3))))
[tex]\sqrt{ - \sqrt{3} + \sqrt{3 + 8 \sqrt{7 + 4 \sqrt{3} } } } \\ [/tex]
Step-by-step explanation:
Given that: √[-√(3)+√{3+8√(7+4√(3))}]
= √[-√(3) + √{3+8√((√3)² + √(4)² + 2√(4*3))}]
= √[-√(3) + √{3 + 8√(√(3) + √(4))²}] [Since, {√(a) + √(b)}² = a+b + 2√(ab)]
= √[-√(3) + √{3 + 8√(√(3) + √(4))²}]
= √[-√(3) + √{3 + 8(√(3) + √(4))}]
= √[-√(3) + √{3 + 8(√(3) + √(2*2))}]
= √[-√(3) + √{3 + 8(√(3) + 2)}]
= √[-√(3) + √{3 + 16 + 8√(3)}]
= √[-√(3) + √{19 + 8√(3)}]
= √[-√(3) + √{16 + 3 + 2√(3*16)}]
= √[-√(3) + √{(16)² + (3)² + 2√(3*16)}]
= √[-√(3) + √{√(16)² + √(3)²}] [Since, {√(a) + √(b)}² = a+b + 2√(ab)]
= √{-√(3) + √(16) + √(3)}
= √{-√(3) + √(4*4) + √(3)}
= √{-√(3) + 4 + √(3)}
Now, cancel -√3 and +√3.
= √(4)
= √(2*2)
= 2
Answer: Hence, the simplified form of √[-√(3)+√{3+8√(7+4√(3))}] = 2.

Answer:
m∠B = 121
m∠C = 59
Step-by-step explanation:
Angle B:
[tex](10x - 19) = (7x+23)\\10x+(- 19+19) = 7x+(23+19)\\10x=7x+42\\(10x-7x) = (7x-7x)+42\\3x = 42\\3x/3 = 42/3\\x = 14[/tex]
