Answer:

∠NQP = 74°

Step-by-step explanation:

NPQ is a triangle.

We know the sum of 3 angles of a triangle is 180 degrees. So we can write:

N + P + Q = 180

2x + 34 + 2x + 2 = 180

Now, we can solve for x:

$2x + 34 + 2x + 2 = 180\\4x+36=180\\4x=180-36\\4x=144\\x=\frac{144}{4}\\x=36$

The measure of NQP is "2x+2", we plug in x = 36, and find the measure of NQP:

∠NQP = 2(36) + 2 = 74°

Answer:

Step-by-step explanation:

The formula for the volume of a square pyramid is $a^{2} \frac{h}{3}$ . a is your base edge and the h is your height. In this case it would be $5^{2} \frac{7}{3}$ . when you wokr it out it would be 58.333, or 58 which is c.

also you would do 5 x 5 then you would multiply it by 7/3.
