Answer:
a) See figure attached
b) 
c) 
So then the heigth for the building is approximately 30 ft
Step-by-step explanation:
Part a
We can see the figure attached is a illustration for the problem on this case.
Part b
For this case we can use the sin law to find the value of r first like this:


Then we can use the same law in order to find the valueof x liek this:


And that represent the distance between Sara and Paul.
Part c
For this cas we are interested on the height h on the figure attached. We can use the sine indentity in order to find it.

And if we solve for h we got:

So then the heigth for the building is approximately 30 ft

Answer:
B. 11.85% = 12%
Step-by-step explanation:
500 * .10 + 300 * .15 = 50 + 45 = 95.
95/800 = .11875
.11875 = 11.875%
4m + 7 = -3m + 49
4m + 3m = 49 - 7
7m = 42
m = 42/7
m = 6
So, your final answer is 6
Hope this helps!
