Question

The length of the hypotenuse, line segment AC, in right triangle ABC is 25cm. The length of the line segment BC is 15cm Which is the approximate measure of angle ACB

Answer 1

the answer is 53.1 degrees

Answer 2

The approximate measure of the angle ACB is 53 degrees

Properties of a right angle triangle:

• One of its angle is 90 degrees
• The angles and side can be found using trigonometric ratio like sine, tangent and cosine.

The approximate measure of angle ACB can be found as follows:

cos C = adjacent / hypotenuse

Therefore,

cos C = 15 / 25

cos C = 0.6

C = cos ⁻¹0.6

angle ACB = 53.1301023542

angle ACB ≈ 53°
