Right triangle ABC is shown.
Which equation can be used to solve for c?
3 m
A
O sin(509) = 3
O sin(509) = {
O cos(509) =
O cos(509) = ?
W wa

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
