the length of the shadow of a pole on level ground increases by 90m when the angle of elevation of the sun changes from 58 degre
Mama L [17]

Step-by-step explanation:

(A) Let a triangle be formed with height of pole h, length of base b and angle of elevation 58°. (Due to lack of a figure).

Tan 58° = h / b = 1.6

(B) Let another triangle be formed with height of pole h, length of base (b + 90) and angle of elevation 36°. (Due to lack of a figure).

Tan 36° = h / (b + 90) = 0.72

(C) <u>Simplifying the two equations</u> :

1.6b = 0.72b + 64.8

b = 64.8 / 0.88 = 73.6 m

h (height of pole) = 1.6 * 73.6 = 117.76 m

Can you please help me again.
Jobisdone [24]

Answer: h = 17

Step-by-step explanation: As a general rule, if an equation has any fractions in it, try to get rid of those fractions as soon as possible.

The quickest way to get rid of a fraction is to multiply both

sides of the equation by the denominator of the fraction.

So in this problem, we can get rid of the fraction in our

first step by multiplying both sides of the equation by 4.

On the left, the 4's cancel and on the right, 1(4) is 4.

Now we have h - 13 = 4.

Since 13 is being subtracted from <em>h</em>, to get <em>h</em> by itself,

we need to add 13 to both sides of the equation to get h = 17.

Now, we can check our answer by plugging 17 back

into the original equation shown below in italics.

\frac{(17) - 13}{4} = 1

\frac{(4)}{4} = 1  true statement

There are 60 players on a high school football team. The ratio of juniors and seniors to freshmen and sophmores on the team is 2
nata0808 [166]
You know that the ratio of J&S to F&So is 2:3. You need two numbers that have that same ratio to total 60 players.  When you multiply both numbers by 12, you have a ratio of 2:3 but the number of players is 24 to 36.  Thus, the total players is 60.  When looking at the ratio of Juniors to Seniors, the ratio remains 1:2, but must total 24 players.  Dividing the total players by 3, you can find where 1 part of the players equals 2 parts of the others.  Keeping that same ratio in mind, you are able to calculate that the ratio of Juniors to Seniors is 8:16 but when reduced, still remains a 1:2 ratio.
