This is a bit hard for me. i have no clue at all on this. been trying me you

Well the pyramid surface area is just 4 triangles that are the same shape and 1 square. so the square's area = 4*4 = 16 and a triangle would be 5*4*0.5 = 10 but there are 4 triangles so 4*10 = 40 plus the area of the circle so the answer is 56

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 !

The answer is the numbers between =5 and 5
