Question

the given figure find the value of∠ A, ∠ B and ∠C​

Answer 1

Answer:

∠A = 80°

∠B = 96°

∠C = 4°

Step-by-step explanation:

Step 1:

We know that in a triangle the sum of the angles is 180°.

Step 2:

(5x - 60°) + (2x + 40°) + (3x - 80°) = 180°

=> 10x - 100° = 180°

=> 10x = 280°

=> x = 28°

Step 3:

∠A = 5*28 - 60° = 80°

∠B = 2*28 + 40° = 96°

∠C = 3*28 - 80° = 4°
