Question

Mathematics for Class 7
8. Each of the two equal angles of an isosceles triangle is twice the third angle. Find the angles
of the triangle.
​

Answer 1

Answer:

If the third angle is x, the other two angles are 2x

The measure of the angles of a triangle must add up to 180 degrees

x + 2(2x) = 180

x + 4x = 180

5x = 180

x = 36

The other two angles are 2x = 2 * 36 = 72

The three angles are 36, 72, and 72 degrees

Answer 2

36

Step-by-step explanation:

2x+2x+x=180

5x=180

x=180/5

x=36

2x=2*36=72

2x=2*36=72 ANSWER
