Answer:
m<EFG = 72°
m<GFH = 108°
Step-by-step explanation:
m<EFG = 2n + 16
m<GFH = 3n + 24
Linear pairs are supplementary, therefore,
m<EFG + m<GFH = 180°
Substitute
2n + 16 + 3n + 24 = 180
Add like terms
5n + 40 = 180
5n + 40 - 40 = 180 - 40 (subtraction property of equality)
5n = 140
5n/5 = 140/5 (division property of equality)
n = 28
✔️m<EFG = 2n + 16
Plug in the value of n
m<EFG = 2(28) + 16 = 72°
✔️m<GFH = 3n + 24
Plug in the value of n
m<GFH = 3(28) + 24 = 108°

Answer:
x = 25.33333333
Step-by-step explanation:
x = 4
76 12
Cross multiply:
x * 12 = 76 * 4
Simplifying
x * 12 = 76 * 4
Reorder the terms for easier multiplication:
12x = 76 * 4
Multiply 76 * 4
12x = 304
Solving
12x = 304
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '12'.
x = 25.33333333
Simplifying
x = 25.33333333
The correct choice is the second one which is 4(2 + y)
3 because it is 9 units but dilated by 3. So 9/3 = 3
