Answer:
Step-by-step explanation:
f(x) = x + 2.....change f(x) to y
y = x + 2....now switch x and y and solve for y
x = y + 2
x - 2 = y....change y to f-1(x)...represents an inverse
f-1(x) = x - 2 <== ur inverse
A and 90-a is the measure of the two angles
a=90-a-6
2a=84
a=42
42° and 48°
X + 9/7 = 10
- 9/7 -9/7
___________
x = 8 2/7
