Answer:

Correct choice is A

Step-by-step explanation:

For the numbers 13 and 88, find the difference 88-13:

since 88-13=75 and $\dfrac{75}{3}=25$ (two arithmetic means tells you there will be three intervals), two arithmetic means will be

13+25=38;
38+25=63.

The only correct sequence is 13, 38, 63, 88.

In order to estimate the height of a building, two students stand at a certain distance from the building at street level. from

enyata [817]

Let h represent the height of the building. Then the difference between the two angle measurement locations is
.. h/tan(39°) -h/tan(50°) = 300 ft
.. h = (300 ft)/(1/tan(39°) -1/tan(50°))
.. h ≈ 758 ft

The height of the building is about 758 feet.
