Select the correct answer. Consider this equation. 275 cos(8) = 5 If 8 is an angle in quadrant II, what is the value of sin(); OA 5 ola OB. V5 5 1 OC. OD. -

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:
