Question

More math pls help. :)

Answer 1

cscθ = 5/4

Explanation:

cscθ = hypotenuse ÷ opposite

we need to work out what is the length of b to to find the opposite

b^2 = 15^2 - 9^2 = 144

b = 12

now we have the opposite side = 12

back to equation cscθ = hypotenuse ÷ opposite

where they hypotenuse = 15, opposite = 12

cscθ = 15 ÷ 12 which is simplified to 5/4
