I need help plsssssssssssssssssssssss

Answer 1

7x + 34 = 90
-34 -34

7x= 56
— —
7 7

x=8; so your answer would be 8.

Answer 2

7x + 34 = 90

-34 -34

7x = 56

Divide by 7 on both sides:

X = 8 degrees

A right angle equals 90 degrees so that must mean angle 7x + 34 must equal to 90 so we solve for x.

A triangle equals = 180 degrees

A quadrilateral equals = 360 degrees

A right angle equals = 90 degrees

A straight line equals = 180 degrees
