Question

In ∆ PQR angle P = 30° angle Q= 90° find angle R​ please give answer step by step ​

Answer 1

Answer:

Measure of angle ORP or R is 60°.

Step-by-step explanation:

Let angle ORP or R be x.

Angle PQR + angle ORP + angle RPQ = 180° (Angle sum property of a triangle)

90° + x + 30° = 180°

120° + x = 180°

x = 180° - 120°

x = 60°

Therefore, measure of angle ORP or R is 60°.

Answer 2

Answer:

The sum of the measurement of the three angle is 180°

∆ PQR = angle P +angle Q + angle R = 180°

30° + 90° + R = 180°

120° + R = 180°

R = 180° - 120°

R = 60°

cheak our answer is right or wrong

30+90+60 = 180 so our answer is Right.
