Answer:

The answer is the third one: x + y + z = 180 degrees

Step-by-step explanation:

in the picture we can tell angle x measures 90 degrees meaning that the third angle of the triangle also measures 90 degrees because the sum of the angles of a triangle is always 180 we can be sure that x + y + z = 180 degrees

Answer:

y + z = x

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle, thus

y + z = x

dmitriy555 [2]

Step-by-step explanation:

Let's say R is the initial radius of the sphere, and r is the radius at time t.

The volume of the sphere at time t is:

V = 4/3 π r³

Taking derivative with respect to radius:

dV/dr = 4π r²

This is a maximum when r is a maximum, which is when r = R.

(dV/dr)max = 4π R²

This is 4 times the sphere's initial great circle area, but not the great circle circumference.  The problem statement contains an error.
