Help me please I give thanks

If you split the shape into a triangle and a rectangle you can work out both areas and add them together The area of a rectangle is length x width so it would be 2x6 = 12in The area of a triangle is base x height divided by 2 so it would be 6x3 divided by 2 which is 9in Then you would add both the areas together to get an answer of 9+12 = 21 So the area is 21in

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 !
