Question

if the measure of one of an isosceles triangle is 40 another angle of the traingle cannot be measure ​

Answer 1

Step-by-step explanation:

The first angle is 40 given

The second angle is 40 as well since its an isosceles triangle.

Sum of all 3 angles is180 for a triangle

therefore 40 + 40 + x = 180

solving, x = 180 - 40 - 40

x = 100

Thus the three angles in the triangle are 40, 40 & 100
