I would help but I cannot read it.
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°
Answer:
6a+6b=ma
?? Not 100% sure, so have someone else answer please too
Answer:
72 in
Step-by-step explanation:
We know that 120 in is equal to the sum of the given height expressions.
(9x) +(7x-8) = 120
16x = 128 . . . . . . add 8 and simplify
x = 8 . . . . . . . . . . divide by 16
9x = girl's height = 9·8 = 72 . . . . inches
The height of the girl is 72 inches.
