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

The measure of the base angles of triangle TIC , that  is ∠C and ∠T is 40°.

Step-by-step explanation:

In Isosceles ,Δ TIC

Given : ∠I= 100°

To find : ∠C= ?, ∠T= ?

Solution:

Isosceles triangle has two equal sides. And angles opposite to equal sides are equal.

So,∠C = ∠T =x

In Δ TIC

∠I + ∠T + ∠C = 180° (Angle sum property of triangles)

100° + x + x = 180°

2x = 80°

x = 40°

∠C = ∠T = x = 40°

The measure of the base angles of triangle TIC , that  is ∠C and ∠T is 40°.

Just took the test!

Step-by-step explanation: D. 40

step-by-step explanation: i dont

55 because 55 + 55 = 110 good luck babe
