Solve the equation for x.
2 answers:
We move all terms to the left:
9(2x+15)-(45)=0
We multiply parentheses
18x+135-45=0
We add all the numbers together, and all the variables
18x+90=0
We move all terms containing x to the left, all other terms to the right
18x=-90
x=-90/18
x=-5

You didn’t upload any picture maybe you forgot to
take h=29
ø=39
b=q
then
cosø=b/h
cos39=q/29
0.777×29=q
q=22.53
