if a fire ranger on a tower 150 ft spot a fire at an angle of 30-depression, how many feet away is the tower is from the fire.
By using trigonometric relations, we will see that the distance to the fire is .173.21 ft
How to find the distance to the fire?
Here we can compare this with a right triangle. We know that one angle on the right triangle is 30°, and the adjacent cathetus to that triangle is 150ft.
Now, we want to find the hypotenuse of said triangle, which is the distance to the fire.
So we can use the trigonometric relation:
cos(a) = (adjacent cathetus)/(hypotenuse).
Replacing what we know, we get:
cos(30°) = 150ft/hypotenuse
hypotenuse = 150ft/cos(30°) = 173.21 ft
So the distance to the fire is 173.21 ft

Line segment GH has endpoint G(10,11) and H(−2, −7).
Part A: The point Z lies on segment GH and is located at (6, 5). What is the ratio of GZ: ZH?
Part B: Find the coordinates of Q such that HQ: GH = 1: 6.
Answer:
(-1,-2)
Step-by-step explanation:
The given coordinates are ,
G ( 4 , 10)
H ( -2 , -6)
Midpoint can be calculated by finding the mean of x coordinates and y coordinates . As ,
→ Midpoint = ( 4-2/2 , 10-6/2)
→ Midpoint = ( -2/2 , -4/2 )
→ Midpoint = ( - 1 , -2)
Hence the midpoint is (-1,-2)PART B:To find out the midpoint,here's the formula: ((x1+x2)÷2 , (y1+y2)÷2)
Thus,the midpoint of QS is
((4+(-2))÷2 , (10+3)÷2)
=(1 , 13/2)

Find the sum of the first 21 terms of the arithmetic series.
46 +53 +60 +67+ ...
Answer:
2436
Step-by-step explanation:
The sum of n terms of an arithmetic series is given by the formula ...
Sn = (n/2)(2a +d(n -1))
where a is the first term, and d is the common difference.
__
This series has ...
a = 46
d = 53 -46 = 7
n = 21
So, the desired sum is ...
S21 = (21/2)(2(46) +7(20)) = 2436
The sum of the first 21 terms is 2436.
