Let 2x = both base angles
Let 1/2(x) = third angle
Sum of the angles = 180 degrees
Equation:
2x + 1/2(x) = 180
2x + .5(x) = 180 -->converting 1/2 to a decimal
Solve for x. Don't forget to list each angle!
The third angle in an isosceles triangle is 1/2 as large as each of the two base angles. Find the measure of each angle.
