Question

Please I need help (dont answer if you don't know ill report you)

Answer 1

Answer:

x = 12

Step-by-step explanation:

In this figure the name is 90° which means it is perpendicular

So it means that if you add two of the angles you will get 90°

We can write it in the form of algebraic expression,

$3x + x + 42 = 90 \\ 4x + 42 = 90 \\ 4x = 90 - 42 \\ 4x = 48 \\ x = \frac{48}{4} \\ x = 12$

This is your answer :))

Answer 2

x+42+3x=90

4x+42=90

4x=48

x=12
