Question

What is X equal to in this problem?

Answer 1

X is 80 because the inside on a triangle always adds up to 180 while the outside is 360 so 51+49=100 so 100-180=80 boom the answer

Answer 2

Answer: X=80

Explanation:

1. Know that all angles COMBINED in a triangle is 180, so we can use the two angles to setup the equation for the last one, since the total angle must be 180 then x added to those angles must add up to 180.
2. so we get the equation x+59+41=180.
3. x+100=180, subtract 100 from both sides to isolate x.
4. x=80.
