Answer:

x = 27°

Step-by-step explanation:

m<D

m<CBE = 63° (Given)

m<CBE = m<ABD (vertical angles)

m<ABD = 63° (substitution)

x = 180 - (m<ABD + m<D) (Sum of triangle)

x = 180 - (90 + 63)

x = 27°

A stick 42 inches long is broken into two pieces, so that one piece is twice as long as the other one. How long are the two piec

krek1111 [17]

Total length of stick = 42 inches.

Let the shorter piece be x inches.

Thus, the longer piece is 2x.

2x + x = 42

3x = 42

x = 14

Therefore, the length of the two pieces are 14 inches and 28 inches.

I need to know how to solve this anyone?

I can't make out what the radius of the sphere is, but the equation you're looking for is:

$V=\frac{4}{3}\pi r^3$

For example:

If the radius of a sphere is 5 m, it's volume would be,

$V=\frac{4}{3}\pi (5)^3$

$V=\frac{4}{3} (3.14)(5)^3$

$V=\frac{4}{3}(3.14)(125)$

$V=523.6 m^3$
