Answer:
one term is in this expression
Step-by-step explanation:
This is a bit of a guess, but I think probably a) +4 and also a) -215
Answer: -124
Step-by-step explanation: -83-41
subtract and it suppose to give you -124
Area of the base = 1/2 * 10 * 5sqrt3 = 25 sqrt3
Total surface area = 25 sqrt3 + 3 * 1/2 * 10 * slant height = 214.5
25 sqrt3 + 15h = 214.5
15h = 214.5 - 25 sqrt3
h = (214.5 - 25sqrt3() / 15
= 11.41 cm to nearest hundredth
