Question 319202: Last question.
If the vertex angle of an isosceles triangle is 56�, find the measure of each base angle.
I'm not good with finding the measurement of angles. It will be a great help if you can help me figure out this problem.

Remember that isosceles triangles have two base angles that are equal to one another. So if 'x' is the base angle, then

Start with the given equation.

Combine like terms on the left side.

Subtract from both sides.

Combine like terms on the right side.

Divide both sides by to isolate .

Reduce.

Answer:

So the solution is which means that the two base angles are 62 degrees each.
