Question

Each of two equal angles of an isosceles triangle is four times the third angle. Find the angles of the triangle.






Let the first angle=4×
the second angle=4×
the third angle=×

sum of three angles=180°

4×+4×+×=180°
9×=180°
×=180°/9
×=20°

First angle=4×20°=80°
second angle=4×20°=80°

Therefore angle are. 20°,80°,80°​

Answer 1

Answer:

yes

Step-by-step explanation:

it is right because when we sum it 180° comes
