Question

What were the lengths of the legs of a right triangle in which measures 19 degrees and the hypotenuses 15 units long
A.) 9 units, 12 units
B.) 11 units, 10.2 units
C.) 4.9 units, 15.8 units
D.) 4.9 units, 14.2 units
E.) 5.2 units, 14.1 units

Answer 1

Answer:

The legs of a triangle with a hypotenuse that measures 15 units long have lengths that are equal to 15 times the sine or cosine of the given angle.

                     leg 1 = (15 units) x (cos 19) = 14.18 units

                     leg 2 = (15 units) x (sin 19) = 4.88 units

The lengths of the legs are 14.18 units and 4.88 units.
