Question

 Use the given information to find the value of x. Then, find the measure of angle ADC.

Answer 1

60degrees

Explanation

To get the angle x, you must first know that the sum of angle at a point is 360degrees. Hence;

x + <ADB + <CDB = 360

x +150 + 150 = 360

x+ 300 = 360

x = 360 - 300

x = 60

Hence the value of x is 60degrees
