Answer:
35°
Explanation:
Complementary angles are angles that sum up to 90° when added.
- We can write the following equation to find the measure of ∠1.
2x - 13 + 2x + 7 = 90°
4x - 6 = 90°
- Add 6 to bot sides of the equation.
4x = 96°
x = 24
Now replace x with 24 in the expression to find the measure of angle 1.
2×24 - 13 = 35°
