Answer:
x³=27
cuberoot√x³=cuberoot of 27
x=3
Angle 1 = 134
angle 2 = 46
explanation:
angle 1 is a supplementary with 46
angle 2 is alternate interior with 46
Yes ABD=CBD since they both are just half of the triangle
A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.
I believe the answer is D
if you fold it all together using the dotted line, it looks that it will all fit together and look like the above shape
hope this helps
