Answer:

x = 20
y = 114°

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the remote interior angles.

(3x +6)° = 31° +35°

3x +6 = 66 . . . . . . . . . . divide by °, collect terms

3x = 60 . . . . . . . . subtract 6

x = 20 . . . . . . . divide by 3

The value of y is the supplement of (3x+6)°, and of the sum (31 +35)°.

y = 180° -66° = 114°

The values of x and y are 20 and 114°, respectively.
