Question

one of the two angles of an isosceles triangle measure 65 degree. find the measure of the third angle ​

Answer 1

Answer:please mark my answer as brainliest

Step-by-step explanation:

Given that the one of the two equal angles is 65°

The other one of the equal angles must also be 65°

Find the third angle:

Sum of angles in a triangle = 180°

third angle = 180 - 65 - 65 = 50°

Answer: The angles are 50°, 65° and 65

Answer 2

Answer: The third will be 50 degrees

Step-by-step explanation:

In an isosceles triangle, any two will be angles will be equal..

So let the two equal angles be 65 degrees

<A + <B + < C = 180

<A = <B

65 + 65 + <C = 180

130 + <C = 180

<C = 180 - 130

Therefore <C = 50
