Question

Q.15. In a A PQR, the sides PQ and PR are produced to S andT respectively. Bisectors of angle SQR and angle QRT meet at thepoint o. If P = 66°, then what is the value of angle QOR?a. 47b. 50°c.57

Answer 1

Answer:

57°

Step-by-step explanation:

Theorem -:

When the angle bisector of any two exterior angle of a triangle meets a point the 'O', then the measure of angle O is = 90 - 1/2(measure of third interior angle)

In this the third interior angle is 66°.

Therefor-:

∠o = 90 - 1/2 66°

∠o = 57°

Hope this will help you.!!!
