Question

9. The ratio between the vertical angle and base angle of an isosceles triangle is 2:5. Find the angles of
the triangle.​

Answer 1

Answer:

2:5

Step-by-step explanation:

2x+5x=180

7x=180

x= 180/7

x=25.71

Answer 2

Step-by-step explanation:

Angles are in the ratio 2:5

Let x is common factor. Then angles are 2x, and 5x ; sum of angles = 2x+5x = 7x = 180 or x = 20;

angles are 40 and 100
