Answer:
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
23 + 35 + A=180
58 + a =180
-58 -58
-------------------
A = 122 degrees
