Answer:
146
Explanation:
Given;
∠A and ∠B are supplementary. The measure of ∠A is 34°.
To Find;
What is the measure of ∠B?
Note:
Supplementary = 180 degree
Solve:
Since supplementary = 180 degree
34 + x = 180
Subtract 34 from both sides
x + 34 - 23 = 180 - 34
Simplify
x = 146
Hence, the measure of ∠B is 146
