What’s the equivalent decimal for 7 1/3?

Since there are 7 wholes, the whole number of it would be 7. In order to find the other part, you need to divide the numerator by the denominator. 1 divided by 3 = 0.333 (it keeps going, so put a line over it to show that it keeps going, or round it)

so, it would be

7.333

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 !
