Question

In the triangle below, what is sin θ?

Answer 1

sine (theta) = opposite / hypotenuse
sine (theta) = 10 / 26
sine (theta) = 5 / 13
sine (theta) = 0.3846153846

(Looking up the arc sine (0.3846153846), we find that
angle theta = 22.62 Degrees)

Answer 2

Sin theta = 10/26 = 5/13

Hope it helps.
