Question

two angles of a triangle are equal and the third angle is 80 degree find the measure of one of the equal angles​

Answer 1

Answer:

The measure of two angles is 100°.

So one of the angle has measure of 50°.

Explaination :

80° + x + x = 180° ( x is the angle )

x + x = 100.

2x = 100

x = 50°

Answer 2

Answer:

50

Step-by-step explanation:

There are 180 degrees in a triangle. If two angles are equal, and we know that one angle is 80 degrees, we can write an equation 80+2x=180. We subtract the 80 from both sides to get 2x=100. We then divide by 2 on both sides to get x=50.

Since we knew that the last two angles would add up to 100, and that they were equal, we know that we just have to divide by 2 to get the individual angle measure.
