asked • 01/15/21If sinP = 2/7, what is tanQ?
I got 3√5/7 but I was told that the correct answer was 3√5/2 but I don’t know how they got that.

sin P = opposite / hypotenuse = 2 / 7
So adjacent = √ (72 - 22) = √ 45 = √ 9 x 5 = √9 √5 = 3√5
Tangent = opposite / adjacent = 2 / (3√5).
(The correct answer is this, not 3√5 / 2).

Sorry misread it, Q is the other angle not 90, so tan Q = adjacent / opposite so your correct answer is correct
