Margie wants to draw a pair of complementary angles. She drew one angle that had a measure of 35°. What should be the measure of the second angle?
A. 35°
B. 55°
C. 65°
D. 145°
Since complementary angles add up to 90°, the second angle should have a measure of 90° - 35° = 55°. Therefore, the answer is B. 55°.
To find the measure of the second angle that is complementary to the first angle of 35°, we can use the fact that complementary angles add up to 90°.
So, to find the second angle, we subtract the measure of the first angle from 90°.
90° - 35° = 55°
Therefore, the measure of the second angle should be 55°.
Therefore, the correct answer is B. 55°.
