Question

the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?

Answer 1

Answer: x=23 and the angle relation used was supplementary angles

Explanation:

first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Answer 2

Answer: x = 23

Explanation

The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.

(angle ABD) + (angle DBC) = 180

(134) + (2x) = 180

2x = 180-134

2x = 46

x = 46/2

x = 23
