31-71=102

7 0

Answer:

The correct answer is C

Step-by-step explanation:

Helpful fact- All triangles are 180 degrees

Angle 1 = 31 degrees

Angle 2= 71 degrees

X= Angle 3

Y = Angle 1&2 Sum

So by adding Angles 1 & 2 we get a sum  to subtract from 180 and get a difference. That difference will be Angle 3.

Angle 1 + Angle 2 = Y

180 - Y= X

31 + 71 = 102 degrees   Y= 102 degrees

180 - 102 = 78 degrees  X= 78 degrees

which has a greater effect on the volume - changing the radius by a given amount or changing the height by the same amount/ why?
AURORKA [14]
Assuming we’re talking about a cylinder, whose volume formula is V = pi r^2 h…

It will have a greater effect to change a variable’s value that has a greater power on it.

Changing h from 1 to 2 doubles the volume.
Changing r from 1 to 4 quadruples the volume, because 1^2 = 1 and 2^2 = 4. The effect of the change on r is amplified by the power.
