Answer:
Step-by-step explanation:
angle:: x
complemet: 90-x
supplement: 180-x
Equation:
180-x = 4(90-x)+60
180-x = 360 -4x + 60
3x = 240
x = 80 degrees (the angle)
90-x = 10 degrees (the complement)
180-x = 100 degrees (the supplement)
Answer:

Step-by-step explanation:
The lateral surface area of a cone is given by
, where
is the radius of the base of the cone and
is the cone's slant height.
Solving for
:

*Note: It is implied that the surface area of 200 pi square inches is lateral surface area and not total surface area, because it is impossible to obtain a total surface area of 200 pi with a radius of 10 inches.
Answer:
five congruent triangles
Step-by-step explanation: The area of the pentagon will be the sum of the five congruent triangles formed. The area of one of these triangles is equal to the side of the pentagon*height/2
