Question

For what value of x is the figure a rectangle? Please help

Answer 1

X=8


(2x + 42) + 4x = 90 degrees

Add 4x + 2x to get 6x + 42 = 90

Then, subtract 42 from both sides to get, 6x = 48

Lastly, divide both sides by 6 to get your final answer of X = 8.

Answer 2

x = 8

Hope this helps!

Explanation:

( 2x + 42 )° + ( 4x )° = 90° ( right angle )

6x + 42 = 90

6x = 90 - 42

6x = 48

x = 8
