The answer is x=5 because 24-3-5=16 so you have to get those 2 sides to equal 16....2*5=10+1=11 then add 5 and you get 16

A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n

M + f + a = 82
m = 7a + 1
f = 1/2m.....f = 1/2(7a + 1).....f = 3.5a + 0.5

7a + 1 + 3.5a + 0.5 + a = 82
11.5a + 1.5 = 82
11.5a = 82 - 1.5
11.5a = 80.5
a = 80.5 / 11.5
a = 7......7 adults

m = 7a + 1
m = 7(7) + 1
m = 49 + 1
m = 50 <=== 50 male students

f = 1/2m
f = 1/2(50)
f = 25 <=== 25 female students

The given question is on trigonometry which requires the application of required function so as to determine the value known. So that the length of the guy wire is 67.0 feet.

Trigonometry is an aspect of mathematics that requires the application of some functions to determine the value of an unknown quantity.

Let the length of the guy wire be represented by l, and the angle that the guy wire makes with the stake be θ. So that applying the appropriate trigonometric function to determine the value of θ, we have:

Tan θ = $\frac{opposite}{adjacent}$
