You are designing a box like the one shown The measure of Z1 is 70°. Find m2 and 23.
m22-0
m23 - 0
Explain why ZABC is a straight angle.
In the closed box, 22 and 4 form a linear pair, so m_2+m4 -0. These angles do not change in the open box, so m_2+m_-0
and ZABC is a straight angle,

there is no picture in order for this question to be answered

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

i think da answer is

d.square root of 3
