Answer:
136
Step-by-step explanation:
180(4-2)
=180(2)
=360
2x+3x+4+4x+16+2x+10=360
11x+30=360
11x=360-30
11x=330
divide both side by 11
x=30
Substitute the value
A:2(30)
=60
B:3(30)+4
=94
C:4(30)+16
=136
D:2(30)+10
=70
Add all to check
60+94+136+70
=360
Therefore the largest angle is 136
Answer: C (-7/18)
Step-by-step explanation: you flip the denominator and numerator and keep the negative
It would be 6+4, which equals 10. Then, subtract 104 ft minus 10 to get 94 ft in depth.
Answer: 117.45 ft²
Step-by-step explanation:
There is a general formula for calculate the surface area of a regular pyramid. This is:
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
The perimeter is:
The base is an hexagon, therefore you can find the area by using the formula for the area of a regular polygon:
The slant height can be calculated with Pythagorean theorem. The hypotenuse is the slant height and the other legs are 6ft and:
Then:
Then, the surface area is:
