14 trout out of 50 total fish. The total amount of fish in the lake is 7500. Let’s make this into a proportion.

14/50=x/7500

x represents how much trout is in the lake, we don’t know yet, but we’ll find out.

First, cross multiply.

14*7500=105000
50*x=50x

Now let’s turn this into an equation.

50x=105000
Divide both sides by 50
50x/50=x
105000/50=2100

x=2100
Out of the 7500 fish in the lake, 2100 were trouts.

A 25 foot ladder is leaning against a house. If the angle of Elevation of the ladder is 72 degrees:
coldgirl [10]

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

<u>for the first blank</u>

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

<u>for the second blank</u>

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x
