Respuesta :

The third angle would be 40°

This is because all angles of a triangle add up to 180°

If we know two sides we can figure out the third by adding up the two sides we know and subtracting them from 180°

The final answer when subtracting is 40°

Have a great day!

Answer: 40 degrees

Step-by-step explanation:

A triangle's angles will always add up to 180 degrees. You would solve this problem by either adding up the two angles you already have and then subtracting that answer from 180, or you can do 180-60-80 = 40
