I really need help and I’m struggling anybody have an answer key to this???

Angles 1, 4, 5 and 68 degrees are equal.

angles 2,3,6 and 7 equal 112 degrees

Step-by-step explanation:

This is 2 parallel lines cut with a transversal line

each line adds up to 180 degrees so 180-68 = 112

this solves both 6 and 7 with 5 being adjacent

since it is parallel lines corresponding angles are equal, hence 1,4,5 and 68 are equal, then 2,3,6,7 are equal.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
