Question

Find the values of sin a and tan a, if a is the measure of an acute

angle in a right triangle and
cos a= 0.6

Answer 1

Explanation:

Acute angle means less than 90 degrees....so it is in the first Quadrant and sin and cos will be positive values

Trig identity

sin^2 + cos^2 = 1

sin^2 + .6^2 = 1 shows sin = .8

The tan = sin/ cos = .8/.6 = 1.33
