Question

Find the reasons the unknown angles in each triangle drawn below​

Answer 1

Step-by-step explanation:

GIVEN: angle PQS = 115°

TO FIND: X AND y

PROOF:

x + 115° = 180° ( linear pair)

x = 180° - 115°

• x = 65°

By Exterior angle Property of ∆

x + y = angle PQS

65° + y = 115°

y = 115° - 65°

• y = 50°
