• We know , the sum of all 3 angles in a triangle is 180°.
• It is known as Angle Sum Property.

By using this Property ,

4x + (x+10) + (x-5) = 180°

4x + x + 10 + x - 5 = 180°

6x +5 = 180°

6x = 175°

x = 175/6°

Angles →

1. 4x = 4×$\frac{175×4}{6}$ = $\frac{350°}{3}$
2. x + 10 = $\frac{175}{6}$+ 10 = $\frac{235°}{6}$
3. x - 5 = $\frac{175}{6}$- 5 = $\frac{145°}{6}$
