The measure of angle Y is 45, and the measure of angle Z is 70z What is the measure of angle W

If it is referring to a triangle then the answer is 65

Step-by-step explanation:

Each triangle has three angle that have a sum of 180 degrees. if the first 2 equal 115 then the third will equal 65.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
