Hello,
We know all triangles have 180 degrees so we can set up the following equation:
Let x represent one angle of the equal angles y represent the third angle. We can set up 2 equations:
2x+y=180
y=2x-16
Substitute:
2x+2x-16=180
Combine like terms and add 16 to get:
4x=196
x=49
So we know the 2 equal angles are each 49 degrees. The third angle is 82 degrees.
Make sense?
