Question

Find in angles of an isosceles triangle whoes equal and non equal angles are in the ratio of 3:4

Answer 1

Answer:

Angles are 54 degree, 54 degree and 72 degree.

Step-by-step explanation:

Let the equal angle be 3x and non equal angle be 4x.

Then,

3x + 3x + 4x = 180

10x = 180

x = 18 degree

Equal angle= 3x = 3 x 18 = 54 degree

Non equal angle= 4x = 4x 18 = 72 degree.
