Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
There are two main types of exponential functions: exponential growth<span> and </span><span>exponential decay</span>
8x-8= 5x-35
8x-8=5x=-35+8
3x=-35+8
3x =27 then divide both sides by 3 and 27/3 is -9
But in the long run download Photo-math it is a HUGE help it will show you the steps too
Answer:
t =
Step-by-step explanation:
solve for t
h = -a + 1; multiply both sides by -2
-2h = a - 2; add 2 to both sides
-2h + 2 = a; divide by a
(-2h + 2) / a = ; take the square root
t =
