Answer:

Step-by-step explanation:
Surface area of this shape = area of 2 triangles + area of 3 rectangles

16 positive and 26 negative.......16 - 26 = -10 <==
0, because 1/2 = 0.50. therefore .07 is more closer to 0
Answer:
if thisa is a triangle then 180-30+30 = 120 degree and we say all angles on a triangle add up to 180
Then reaply the rule changing 180 to 360 on all 4 sided shapes
180(n-2) to all other shapes.
ie) pentagon 180(n-2) = 540
continue with 540-30-30 = 480 etc....
