Question

the adjacent angles of a Trapezium ABCD in which ab parallel to CD are 2 X + 50 and 2x - 10 find the measures of the angles ​

Answer 1

In a Trapezium, the adjacent angles are supplementary.

Hence, 4x + 40 = 180°

x = 35°

Angle ADC = 60° = Angle ABC

Angle DAC = 120° = Angle DCB

Answer 2

Answer:

2x + 50 + 2x-10=180

4x +40=180

4x=140

x=35
