You can put this solution on YOUR website! One angle measure is an isosceles triangle is 100 degrees.what is the measure of each of the other two angles
-----
The sum of the angles is 180.
The 100 degree angle cannot be a base angle as then
the sum of the base angles would be 200 degrees.
---
The 100 must be the vertex angle.
---
Let the base angles be "x" and "x":
Equation:
x + x + 100 = 180
2x = 80
x = 40 degrees.
Each of the base angles is 40 degrees.
