Question

Please help me! Lines p and q intersect to form adjacent angles 1 and 2. If m<1=3x+18 and m<2= -8y-70, find the values of x and y so that p is perpendicular to q.

Answer 1

if I am right, adjacent angle add up to 180 so


but it also say this
" find the values of x and y so that p is perpendicular to q. "

which mean each of them are 90

Answer 2

3x+18 =90
x=24

Answer 3

-8y-70=90
y=-20

Answer 4

Thanks so much!! iVe been stuck on this problem for like an hour
