Question

A right triangle includes one angle that mesures 30 degrees. What is the measure of the third angle?

Answer 1

The third angle is 60 degrees. A triangle has 180 degrees so 180-30-90=60

Answer 2

Answer:

The  third angle is 60°

Step-by-step explanation:

Properties of right triangle.

1) One angle should be 90°

2) Hypotenuse² = Base² + Height²

To find the third angle

It is given that, one angle of right triangle measures 30°.

One angle is 90°

By using angle sum property we can find third angle.

Let third angle be 'x', then we can write

x + 30 + 90 = 180

x + 120 = 180

x = 180 - 120 = 60

Therefore third angle is 60°
