Question 413239: Each of the equal angles of an isosceles triangle is twice as large as the third angle. What is the measure of each angle?
I know that all of the angles equal 180 degrees. I am stuck as to how to solve this word problem. Please help.
Thanks,

You can put this solution on YOUR website!

let third angle = x ,then others two angles are 2x and 2x.
x + 2x + 2x = 180 (sum of 3 angles)
=> 5x = 180
=> x = 180/5 = 36

so, angles are 36, 72 and 72.
