Answer:
angle of elevation will be 
Step-by-step explanation:
Given,
height of tower = 150 ft
height of tower = 1200 ft
So, total height of peak of tower = 1200 + 150
= 1350 ft
distance of user from cell tower = 5 miles
= 5 x 5280 feet
= 26,400 feet
Since the height of user from sea level = 400 ft
so, height of peak of tower with respect to user = 1350 - 400 ft
= 950 ft
If the angle of depression is assumed as 
, then we can write
So, the angle of elevation will be
Answer:
6
Step-by-step explanation:
90
-------------------
10 + (3^2 - 4)
first we look at the parenthesis. take 3 to the second power, and it equals 9
90
------------------
10 + (9 - 4)
next, still in the parenthesis you subtract 4 from 9
90
--------------
10 + (5)
next add 10 plus 5
90
------- = 6
15
now divide 90 by 15 and you get your answer, 6
The first thing to do is to substitute the b and c. The equation will look like this, a+3a+5a=180. Then you must add the a's all together because they are all the same, remember that "a" represents 1. It will look like this in plain 1 + 3 + 5. Then the equation is 9a = 180. to get the "a" you must eliminate or divide the equation into 9 and it will look like this, <u>9a</u> = <u>180</u> Then the answer will be a = 20
9 9
Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine
