All angle in a triangle add up to 180 so we can add all of these angle measures and set them equal to 180.
80+ 2x+2 +5x =180 combine like terms and solve for x
7x= 180-82
x=98/7
x=14

The 3 angles of a triangle need to = 180 degrees

80 + 2x+2 + 5x = 180

 combine like terms: ( 80+2) and 5x +2x)

82 + 7x = 180

subtract 82 from each side:

7x = 98

divide both sides by 7

x = 98 / 7

x = 14
