tic is an isosceles triangle with vertex angle i find the measures of the base angles of tic if m i =100

Answer 1

Since triangle TIC is an isosceles triangle, the base angles will be equal in measure.

Let x be the measure of each base angle. Since the sum of the angles in a triangle is 180 degrees, we can write:

100 + x + x = 180
100 + 2x = 180
2x = 80
x = 40

Therefore, each base angle of triangle TIC is 40 degrees.
