Question

In Fig. 8.59, find the value of x.

Answer 1

Answer:

COF = DOE = 2x

( vertically opposite angles)

3x + 2x + 5x = 180 (straight line)

10x = 180

x = 18

Please mark it as brainliest :-)

Answer 2

Answer:

BOF = AOE = 5X [VERTICAL OPPOSITE ANGLE]

COF = DOE = 2X [VERTICAL OPPOSITE ANGLE]

3X + 5X + 2X = 180°

10X = 180°

X = 180/10

X = 18°
