julsineya [31]

Given :

Angle of elevation, Ф = 24°.

Distance of Sam from launchpad, D = 5 miles.

To Find :

How high is the rocket.

Solution :

Let, height is h.

We know, tan Ф is given by :

tan \ \phi=\dfrac{h}{d}\\\\tan \ 24^{\circ}=\dfrac{h}{5}\\\\h = 5\times tan \ 24^{\circ}\\\\h = 2.226 \ miles

Hence, this is the required solution.

Which is true about the volume or surface area of these prisms?
pshichka [43]
Your answer is the second option: The surface area of B is greater than the surface area of A.

To find the surface area, I found the area of the three sides shown and added them together, and then multiplied the answer by 2, so:

B:
8 × 2 = 16
8 × 10 = 80
10 × 2 = 20
+
= 116
116 × 2 = 232 cm²

A:
5 × 8 = 40
5 × 4 = 20
8 × 4 = 32
+
= 92
92 × 2 = 184 cm²

So therefore B > A because 232 > 184

I hope this helps!
