Answer:
og angle: 126.8
complementary angle: 53.2
og angle mirror (if any): 126.8
complementary angle mirror (if any): 53.2
Since this is a right triangle and we have an angle and a side we can solve for any other side by using sohcahtoa. Now lets look at what we know we have the angle 35 degrees and the side adjacent to the angle is 10. we are looking for the side opposite to the angle. so we need a formula that uses opposite and adjacent that is toa, tan(angle)=oppisite/adjacent
now lets plug in tan(35)=x/10
x=10*tan(35)
x=7.002 now round to nearest tenth
x=7.0
Answer:
192.92 ft^3
Step-by-step explanation:
volume of a cone =
πr²h
π = 3.14
r = radius ]
h = height
the base of a cone is in the shape of a circle. thus, the circumference of the base is equal to the circumference of a circle
circumference of a circle= 2πr
30.144 = 2 x 3.14 x r
r = 30.144 / 6.28
r = 4.8
Volume = 1/3 x 3.14 x 4.8² x 8 = 192.92 ft^3
Answer:
30
Step-by-step explanation:
10b/a
b = 6
a =2
10(6)/2
10x6 / 2 = 60/2
= 30
Answer:
To fill the sandbox, she would need 15 cubic feet.
Step-by-step explanation:
To find the volume of a box, multiply all of its dimensions together.
6ft * 5ft * 1/2ft = 15ft^3
So, since she bought 20 cubic feet of sand, she should have enough with 5 cubic feet left over.
