Answer:

1 in

4 in 3

8 in 3

27 in

64 in

Step-by-step explanation:

1 in because 1^3 is 1

4 in 3 because 4^3 is 64 ( 4 x 4 = 16 x 4 = 64)

8 in 3 because 8^3 is 512 ( 8 x 8 = 64 x 8 = 512)

27 in because 3^3 is 27 ( 3 x 3 = 9 x 3 = 27)

64 in because 4^3 is 64 ( 4 x 4 = 16 x 4 = 64)

grigory [225]

Answer: 16.91°

Step-by-step explanation:

1. You can draw a right triangle as you can see in the figure attached.

2. Then you can calculate the angle of elevation (α) as following:

$\alpha=arcsin(\frac{opposite}{hypotenuse})$

Where:

$opposite=32\\hypotenuse=110$

3. Now you must substitute these values. Then, the angle of elevation is:

$\alpha=arcsin(\frac{32}{110})$

$\alpha=16.91\°$
