Question

What are the lengths of the legs of a triangle in which one acute angle measures 19 degrees and the hypotenuse is 15 units long?

Answer 1

For plato users the correct option is D.

Explanation:

D. 4.9 units, 14.2 units

Answer 2

sin (19°) = side a / 15
side a = 15 * sin (19°)
side a = 15 * 0.32557
side a = 4.88355

side b^2 = 15^2 - 4.88355^2
side b^2 = 225 - 23.8490606025
side b^2 = 201.15
side b = 14.18
