Answer:
50 degrees
Step-by-step explanation:
50 degrees because angle 2 is its vertical angle
The formula for the volume of a pyramid is:
Volume=(1/3)*(Area of the base)*(Height of the pyramid)
You stated that the pyramid has a 10 by 10 base, so the "area of the base" is 100 squared feet. Also, you stated that the "height of the pyramid" is 8.5 feet.
So, Volume=(1/3)(100 squared feet)(8.5 feet)
V=(1/3)(850 cubic feet)
V=283.33333..... cubic feet
Answer:
Step-by-step explanation:
a + 143 = 180 {Linear pair}
a = 180 - 143
a = 37
37 + 93 + b = 180 {Angle sum property of triangle}
130 + b = 180
b = 180 - 130
b = 40
c + b = 90
c + 40 = 90
c = 90 - 40
c = 50
d + 120 = 180 {Linear pair}
d = 180 - 120
d = 60
? = 60 + 40 {Exterior angle property of triangle}
? = 100
