The perimeter is the sum of the outside dimensions.
b1 = 87 - 32 - 14 - 13 = 28 in.
Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.
Divide area by the amount 1 can covers:
360 / 50 = 7.2 cans, round up to 8 cans are needed.
Answer:
Step-by-step explanation:
we know that the total angles around the big triangle are 180° so, we know the right angle is 90° and we are told that one of the angles is 52° so just find the last angle by
180 = 90 + 52 + X
180 - 90 - 52 = X
38 = X
b = 38°
a = 52°
