Suppose that LMN is isosceles with base LN suppose that M

Given:

In an isosceles triangle LMN, LM=MN.

To find:

The measure of the angles L, M and N.

Solution:

In triangle LMN,

                    (Given)

  (Base angles of an isosceles triangle are equal)

Now,

On further simplification, we get

The value of x is 13. Using this value, we get

Similarly,

And,

Therefore, the measure of angles are .

1/5^2 = 7.56/45
