Answer:
x = 8
Step-by-step explanation:
The sum of the measures of two complementary angles is 90°.
m<C + m<D = 90°
5x + 7x - 6 = 90
12x = 96
x = 8
Answer:
180°
Step-by-step explanation:
Supplementary angles are angles whose sum is 180°. If L and M are supplementary, the sum of their measures is 180°.
