Easy it's like regular subtraction
-2 -2=-4 if it's the same sign you add
-2+4=2 different is subtract

Answer:
complementary angles
Step-by-step explanation:
Complementary angles are (by definition) a pair of angles the have a sum of 90°.
Answer:
60
Step-by-step explanation:
What we know:
- ABD is a straight angle, it measures 180 degrees
- Angle CBA + CBD = 180 degrees
- Angle GFH = CBA (they are alternate exterior angles)
Equation:
GFH + CBD = 180
Substitute:
3x + 6x = 180
Add:
3x + 6x = 180
9x = 180
Divide:
9x = 180
/9 /9
x = 20
Substitute:
GFH = 3x
GFH = 3(20)
GFH = 60
m<GFH is 60°
