If you are looking for the average it it somewhere around 64
Answer:
m∠3 = 119°
Step-by-step explanation:
All the angles must equal 360° when added together. You have two known angles that are right next to each other. If you add m∠1 and m∠2, 119 + 61, it is equal to 180°. This means that m∠3 and m∠4 must be equal to 180° as well and since there are only two lines, it is safe to assume that opposing angles are the same so m∠1 = m∠3 and m∠2 = m∠4.
Answer:
The correct option is (A).
Step-by-step explanation:
The expression Carey is solving is:

Simplify the expression as follows:


So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
For this case, we must find the lateral area of the pentagonal prism shown in the figure.
By definition:

Where:
: Is the lateral area
: It is the perimeter of the base
h: It's the height
Substituting the values we have:
