HELP PLEASE. Solve for x in the diagram.

Step-by-step:

5  = x because the degrees is 90. The problem already gives you 50. so you subtract 50 by 90, 90-50=40. now we need to find what times 8 equal 40, and 5x8=40. I hope this helps

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
