Question

Find m< RQS . How can do I solve this

Answer 1

Explanation:

6x° = (2x + 3)° + 77° (Exterior angle of a triangle = sum of two interior angle )

6x = 2x + 3 +77

subtract 2x from both sides

6x - 2x = 2x - 2x + 3 + 77

4x = 3 + 77

4x = 80

therefore:

x = 20°

angle PQR = 120°

angle RSQ = 43 i.e [(2 x 20) + 3)]
