Question

One of the Equal angles of an isosceles triangles is 50°.find all the angles of this triangle

Answer 1

Answer:

50,50,80

Step-by-step explanation:

the two equal sides is 50,50

50+50+ the third side=180

100+the third side=180

180-100=third side

thenthird side =80

Answer 2

Solution:

Let the third angle be x°.

x + 50° + 50° = 180°

⇒ x° + 100° = 180°

⇒ x° = 180° – 100° = 80°

Thus ∠x = 80°
