Question

In the given trapezium PQRS, ST and RT are the bisector of angle PSR and angle SRQ respectivety. Find angle PQR. [S= 30°, R= 35° and P= 120°]​

Answer 1

Answer:

Angle PQR = 175

Given

1. Angle S =30°
2. Angle R=35°
3. Angle P=120°. Angle sum property of triangle =360°
4. So 30° + 35°+ 120°+x = 360°
5. 185 + x = 360°
6. X = 360°- 185° = 175°
7. Angle PQR = 175°
