Need help I don't understand (geometry).
​

(11,11). The first coordinate in a pair is the x coordinate, which tells you how far to move left of right. The second coordinate is the y coordinate, which tells you how much to move up or down. If you’re translating right, you’re going to add to the first number. If you’re translating left, you would subtract it. If you’re translating up, you add to the second number. If you’re translating down, you subtract from the second coordinate.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
