Question

Find the value of x​

Answer 1

Answer:

3x+2x+90=360

5x=270

x=54

3(54)=132

2x=2(54)=108 degrees

Answer 2

Answer:

angle COF = angle EOD (Vertically Opposite Angles)

angle COF = 2x

angle AOC+angle COF+angle FOB=180°(Linear Pair of Angles)

Therefore,

3x +2x + 90 = 180

5x + 90 = 180

5x = 180 - 90

5x = 90

x= 18°
