Question

Find all three angles of the triangle x-5 x+10 x-35

Answer 1

See below ~

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°
