Question

If angle vsr = 8x+18, find the value of x so that us is perpendicular to vs

Answer 1

Given that vsr=8x+18, the value of x that that will make r is perpendicular to vs can be obtained as follows;
let:
vsr=8x+18=90
solving for x we get:
8x+18=90
8x=90-18
8x=72
x=72/8
x=9
The answer is x=9
