Question

X/2 + x + x + 90 degree=360 degree. Find measure of x.

Answer 1

x/2 + x + x + 90° = 360°

x/2 + 2x = 360-90

(x+4x)/2 = 270

5x = 540

x = 108°
-------------------------------------

Answer 2

x/2+x+x+90=360

x/2+2x+90=360.

x+4x+180/2=360.(by taking lcm).

5x+180/2=360.

5x+180=360×2 (by cross multiplication).

5x+180=720.

5x=720-180.

5x=540.

x=540/5.

x=108.
therefore measure of x=108°
