Answer 1

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)

$\frac{5x}{3} + 80 = 180$

$\frac{5x}{3} = 100$

$5x = 300$

$x = 60 \: {ans}$

∆ 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.)
