Answer:
The height of tower is 322.7 feet.
Step-by-step explanation:
Given
Distance between a building and tower= 250 feet
BCDE is a rectangle .Therefore, we have BC=ED and CD=BE=250 feet
In triangle ABE
AB=195.25 feet
In triangle EDC
ED=127.25 feet
ED=BC=127.25 feet
The height of tower=AB+BC
The height of tower=195.25+127.25=322.5 feet

tan37=r/8
r=8tan37
r≈6 in rise per step (to nearest whole inch)
2b
11*12/6=22 steps needed to climb the 11 ft to the entrance
...

tanα=14/20
α=arctan(7/10)
α≈35° (to nearest whole degree)
..
3b
tanα=21/17
α=arctan(21/17)
α≈51° (to nearest degree)
Well, if you notice, is just an arithmetic sequence, is adding 2 to get the next term.
so the last term is 21, so the one before that has to be 21-2 or 19, and the one before that 17 and the one before that 15.
15+17+19+21.
Answer:
Direct variation problems are solved using the equation y = kx. ... Step 3: Rewrite the equation from step 1 substituting in the value of k found in step 2. ... Example 3 – If c varies directly as the square root of d, and c = 6 when d = 256, find c ...
