Yes it is,it can simplified
Answer:
A=60
The angle measures from least to greatest are 60, 60, 120, 120
Step-by-step explanation:
360=6a
(divide by 6)
60=a
(plug it back in)
2a= 2(60)
2a=120
C = 5(59-32)
C = 5(27)
C = 135
Answer:
36√3 + 144
Step-by-step explanation:
Given that,
base of the pyramid is an equilateral triangle with sides = 12
Formula to calculate total surface area of pyramid
<h3>
[Base Area] + 1/2 × Perimeter × [Slant Length]</h3>
Base Area
1/2 (height) (base)
1/2 (√12²-6²)(12)
6(6√3)
36√3
perimeter of base
sum of all sides = 12 + 12+ 12
= 36
slant height = √10²-6²
= 8
put all these values in the formula above
36√3 + 1/2(36)(8)
36√3 + 144
Total area for the pyramid with the equilateral base =
36√3 + 144
