What is isosceles triangle?A triangle is isosceles triangle when the two sides and two angle of the triangle in equal in measure.
The area of the isosceles triangle is given as,
[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4} }[/tex]
Here, [tex]a[/tex] is the measure of equal sides and [tex]b[/tex] is the measure of third side.
Given information-
The arrows of board game are congruent isosceles triangles connected at their bases.
isosceles triangles are connected at their bases.
The base of each triangle measures 2 centimetres
The perimeter of each triangle is 10 centimetres.
The perimeter of a triangle is sum of all its sides.
As the given triangle is isosceles triangle. Thus both the sides of the triangle should be equal.
Suppose the equal sides is x centimetres. The measure of third side is given which is equal to 2 centimetres. Thus,
[tex]x+x+2=10\\2x=10-2\\2x=8\\x=\dfrac{8}{2} \\x=4[/tex]
Hence the length of the equal sides of the isosceles triangle is 4 cm.
Using the above formula as,
[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4} }\\A=\dfrac{1}{2}\times 2\times \sqrt{4^2-\dfrac{2^2}{4} }\\A= \sqrt{16-\dfrac{4}{4} }\\A=3.871[/tex]
Hence the area of one plastic arrow triangle is 3.71 square centimetre. The approximate total area of the plastic triangles on the spinner is twice of it. Thus,
[tex]A=3.71\times2\\A=7.7[/tex]
Thus the approximate total area of the plastic triangles on the spinner is 7.7 squared centimetre.

Answer:
B
Step-by-step explanation:
y = mx + b
The slope is m.
If it was anything other than 0, the line would have an x in it. The line does not have an x associated with it.
The equation of the line is y = 1
The slope must be 0.

Write the inequality in slope intercept form.
2x-3y>9
Step-by-step explanation:
2x - 3y > 9
the target as slope intercept form is
y = ax + b (or any fitting inequality sign)
so, let's transform the original inequality
2x > 3y + 9
2x - 9 > 3y
2x/3 - 3 > y
or
y < 2x/3 - 3
the slope is 2/3 (always the factor of x). the y-intercept = -3.
What are the ordered pairs of the
solutions for this system of equations?
Answer:
(5, 18 ) ; (- 5, 38 )
Step-by-step explanation:
let y = f(x) , then
y = x² - 2x + 3 → (1)
y = - 2x + 28 → (2)
substitute y = x² - 2x + 3 into (2)
x² - 2x + 3 = - 2x + 28 ( subtract - 2x + 28 from both sides )
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take square root of both sides )
x = ± [tex]\sqrt{25}[/tex] = ± 5
substitute these values into (2) for corresponding values of y
x = 5 : y = - 2(5) + 28 = - 10 + 28 = 18 ⇒ (5, 18 )
x = - 5 : y = - 2(- 5) + 28 = 10 + 28 = 38 ⇒ (- 5, 38 )

A telephone pole, shown at the top of the next column, is 60 feet
tall. A guy wire 86 feet long is attached from the ground to the
top of the pole. Find the angle between the wire and the pole to
the nearest degree
60 ft
86 ft
The angle between the wire and the pole is approximately how many degrees.
(Round to the nearest degree.)
Answer:
45.56
Step-by-step explanation:
need to find the base
86^2 = 3600+b^2
b=61.62
tanx = 61.61/60 = 1.02
x = 45.56
The angle between the guy wire and the pole is 46° (rounded to the nearest degree). Solved, using the heights and distances concept of trigonometric ratios.
What is the concept of heights and distances?The concept of heights and distances is the use of right triangles in real-world examples and solving for missing components using trigonometric ratios in a right triangle.
How to solve the question?In the question, we are informed that a telephone pole, shown at the top of the next column, is 60 feet tall. A guy wire 86 feet long is attached from the ground to the top of the pole.
We are asked to find the angle between the wire and the pole.
We will use the concept of heights and distances to solve the problem.
We let the pole be AB, of height 60 ft. It is perpendicular to the ground.
We let the guy wire be AC, where C is the point from where the wire is connected on the ground, from a distance from the base of pole B.
The length of the guy wire AC is 86 ft.
We let the angle between the guy wire and the pole, that is, angle BAC be θ.
In the right triangle ABC, we can say that the trigonometric ratio:
cos θ = AB/AC {cos θ = base/hypotenuse}
or, cos θ = 60/86,
or, θ = cos⁻¹(60/86) = 45.8° ≈ 46°.
Therefore, the angle between the guy wire and the pole is 46° (rounded to the nearest degree). Solved, using the heights and distances concept of trigonometric ratios.

Answer:
[tex]\sqrt{113}[/tex] = x
Step-by-step explanation:
In right triangles the sum of square length of two legs is equal to square length of hypotenuse:
7^2 + 8^2 = x^2
49 + 64 = x^2 add like terms
113 = x^2 find the root for both sides
