In the diagram, line GH is perpendicular to line IJ. What is the measure of angle 1?


A. 37°

Answers

Answer: B

Explanation: 37+53= 90 and it being perpendicular creates a right angle of 90 degrees
Answer is 53 because these are supplementary angles and they adapt to 180 degrees. You add 37 and 90= 127, and then you subtract 127 from 180.
