Question

Right triangle ABC has hypotenuse AB = 12 and acute angle A = 75°. Find
Leg CB

Answer 1

Leg CB = 11.59 unit (Approx.)

Explanation:

Given:

ABC is a right triangle

Hypotenuse AB = 12

Acute angle A = 75°

Find:

Leg CB

Computation:

Using trigonometry function;

Sin θ = Perpendicular / Hypotenuse

Sin 75 = Perpendicular / 12

0.9659 = CB / 12

Leg CB = 11.59 unit (Approx.)
