Question

I need to find the value of "q" in q/sin30 = 10.0/sin80

Answer 1

q ≈ 5.1

Explanation:

Given

`(q)/(sin30)` =
`(10)/(sin80)` ( cross- multiply )

q × sin80° = 10 × sin30° ( divide both sides by sin80° )

q =
`(10sin30)/(sin80)` ≈ 5.1 ( to 1 dec. place )

Answer 2

q=10sin(30)/sin(80) (that is a fraction)

Explanation:

simplify the equation using cross-multiplication:

sin(80)·q=10sin(30)

divide both sides of the equation by sin (80):

q=10sin(30)/sin(80)
