Answer» Answer: x = 60°, y = 30°, z = 140° Step-by-step explanation: We know that, ∆ ABC is a right triangle So, x + y = 90° (Sum of angles of a ∆ = 180°) x + $\frac{2}{3} x + 80 = 180$ Therefore, (LINEAR PAIR) $\frac{5x}{3} + 80 = 180$ $\frac{5x}{3} = 100$ $5x = 300$ $x = 60 \: {<klux>ANS</klux>}$ ∆ ABC is a right triangle ∆ ABC is a right triangleSo, ∆ ABC is a right triangleSo, x + y = 90° (Sum of angles of a ∆ = 180°) y = 90-60 = 30° $\frac{2}{3}$ x + z = 180° 40 + z = 180° z = 140 ° (Ans.)
