Question

Two equal angles of an isosceles triangle are twice the third angle. Find measure of all angles.​

Answer 1

Answer:72,72,36

Step-by-step explanation:

Let the third angle be x

And sum of all angles of triangle is 180

2x+2x+x=180

5x=180

x=36

2x=2*36=72

Answer 2

Answer:

Each of the two equal angles of an isosceles triangle is twice the third angle find the angles of a triangle .

let,

equal angles be - 2x

third angle be - x

using angel sum property:-

2x+2x+x=180°

5x=180°

x= 36°

2x = 2×36

= 72°

2x = 2×36

= 72°
