Answer :
Answer:
See below ~
Step-by-step explanation:
Given : 3 angles of a Δ
- (x + 5)°
- (x + 10)°
- (x + 15)°
Solving :
- According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°
- x + 5 + x + 10 + x + 15 = 180
- 3x + 30 = 180
- x + 10 = 60
- x = 50
Finding the angles
- x + 5 = 50 + 5 = 55°
- x + 10 = 50 + 10 = 60°
- x + 15 = 50 + 15 = 65°
