Answer:
x =12
Step-by-step explanation:
The two angles add to 90 degrees
4x+4 + 5x-22 = 90
Combine like terms
9x - 18 = 90
Add 18 to each side
9x -18+18 = 90+18
9x = 108
Divide each side by 9
9x/9 = 108/9
x =12
Answer:
f = -8
Step-by-step explanation:
7(f+3)+9=5(f-2)-3f
7f + 21 + 9 = 5f - 10 - 3f
7f + 30 = 2f - 10
5f = -40
f = -8

Answer:
x = 37
Step-by-step explanation:
The angle on the left (x+15) and the angle on the right (4x-20) put together would have to equal 180 since a straight like is 180 degrees. If you add like terms the problem would be 5x-5=180. You would have to add 5 (since its negative in the problem) to 180, making the problem 5x=185. Now you divide by 5 (since it's multiplied by 'x') by both sides, which makes your answer x=37
