To find :
angle of 3xHint :
first we have to find the value of xStep by step expansion:
x + 2x + 3x + 4x + 5x = 180°Why?
Reason: angles that are formed on a straight line is equal to 180°
15x = 180°x = 180°/15x = 12.°. value of x = 12
we need value of 3x
put the value of x in 3x
3 × 1236°REQUIRED ANSWER = 36°
Answer:
[tex]5x + 4x + 3x + 2x + x = 180° \\ 15x = 180° \\ x = 180° \div 15 \\ x = 12° \\ 3x = 12 \times 3 \\ 3x = 36°[/tex]

Answer:
BD = 7 units || BC = 7√2 units
Step-by-step explanation:
(a)
if CA is 14, then CD = DA = 7
[tex]\frac{opposite}{adjacent}= tan(x)[/tex]
[tex]\frac{BD}{7}= tan(45)[/tex]
BD = 7 * tan(45)
BD = 7 units
(b)
[tex]\frac{adjacent}{hypotenuse} = cos(x)[/tex]
[tex]\frac{7}{BC}=cos(45)[/tex]
[tex]\frac{7}{cos(45)}= BC[/tex]

Para encontrar el área de un trapezoide Dylan usa la fórmula A = 1/2(b + b2 )h. Las bases tienen longitudes de 3,6
cm y 12 cm. La altura del trapezoide es 5 cm El área del trapezoide es irracional porque
Answers
Answer:
la altura es irracional, y se multiplica por las otras dimensiones racionales.
Step-by-step explanation:
Dado que un trapezoide tiene bases de 3,6 cm y 12 1/3 cm.
Pero la altura es irracional como raíz cuadrada de 5 cm.
El área del trapezoide es irracional porque se encuentra agregando las dos bases y multiplicando por la mitad de la altura.
La suma de las bases sería racional, siendo la suma de dos números racionales
Pero como la altura es irracional, el área sería el producto de una
racional e irracional, por lo tanto, el área sería irracional.

1) What mistake did I make?
2) What suggestion would you give me to avoid making that same mistake in the future?
Answers
Answer:
1) The mistake u made is in the work step 2 when u transposed 4 to the side of 12 you should have changed the sign. It should have been multiplication.
2) Just recheck it once.
So, x was 48
Step-by-step explanation:
Equation:
x/4 - 5 = 7
Transpose 5 first.
So,
x/4 = 7 + 5
(Remember to change the sign when u transpose 5 to the RHS)
So,
x/4 = 12
Transpose 4.
So,
x = 12 × 4
x = 48
Recheck,
Substitute x with 48
48/4 - 5 = 7
Let's check:
48/4 = 12
Now 12 - 5 = 7
So, 7 = 7

What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Student Council is selling t-shirts and hats for $15 and $12, respectively.
let number of t- shirts sold be x and number of hats be y.
So, 15x+ 12y ≥ 1980
From the graph the inequality gives
x= 130 and y= 165.
Hence, 130 t shirts and 165 hats must be sold.
