The entire system forms a right angle triangle.
Let the height of the bulding be x, then tan 45 = (x - 6)/60
60 = x - 6
x = 60 + 6 = 66

Therefore the height of the building is 66 feet.

Alejandra has five hair ribbons measuring 8,13,11,9, and 13 inches long what is the median length of the ribbons
Digiron [165]
I'm afraid it's not 11 (unless you can round the result up, but there is no mention about it).

8 + 13 + 11 + 9 + 13 = 54
54 / 5 = 10,8

Firstly you sum all the numbers and then you divide the result by the amount of the summed up numbers.

The Clark family must pay $2,820 in property tax on their home this year. The house payment $752 per month. What is their paymen
Harlamova29_29 [7]
It's actually easier than it seems. if the tax is paid in equal payments every month and the total throughout a year (12 months) is $2,820, you have to find out how much they pay every month
so divide the total by the number of months
2,820/12=235
they pay $235 in taxes every month
to find out the total of the taxes and the house payment, just add the monthly tax and the monthly house payment.
235+752
and your answer is the sum
