Question

the vertax angle of an isosceles triangles is 70°. Find the other two angles​

Answer 1

Answer:

70° and 40° because two sides and two angles of isosceles triangle are equal so 70+70+40=180°

Answer 2

Step-by-step explanation:

in Δ ABC

∠ a = 70°

let the base angles be x

∴ x +x+70 = 180

2x + 70 = 180

2x= 180 - 70

2x = 110

x = 110\2

∴ x = 55

∴the base angles are 55°

So, the angles are 55°,55°,70°
