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