Step-by-step explanation:
Complementary angles are angles that add up to 90°.
We have C and D as complementary.
Their sum is:
Substitute values and solve for x:
- 8x + 5x - 1 = 90
- 13x = 90 + 1
- 13x = 91
- x = 91/13
- x = 7
720 degrees = 12.566 radians
Answer:
5x + 2x + 7x
Step-by-step explanation:
X=-9
-x=9 so x=-9 since you inverse the sign
