Answer:

100

Step-by-step explanation:

A triangle would add up to 180 degrees, therefore you would just follow the steps below for this problem:

35+45= 80

80+x=180 (subtract 80 from both sides)

x= 100°

Answer:

x=100

Step-by-step explanation:

The sum of a triangle is always 180 so you'd add the given number together which would be 80 and subtract the from 180 so it would look like this 45+35+x=180
