Answer:

Step-by-step explanation:

Let us first write an equation. Using the SOHCAHTOA rule, we should know that the tangent of an angle equals it's $\frac{opposite}{adjacent}$ . The opposite of our given 20° angle is 9, and the adjacent side is x.

$tan(20$ ° $)=\frac{9}{x}$

$0.364=\frac{9}{x} \\x=\frac{9}{0.364}\\x=24.7$

I hope this helps! Let me know if you have any questions :)

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre

natta225 [31]

Answer:

10 rabbits

Step-by-step explanation:

Let us represent

Number of rabbits = x

Number of squirrels = y

Number of deer = z

Katniss caught three times as many squirrels as deer.

y = 3z

She also caught five less rabbits than squirrels.

y = x - 5

The total number of animals she caught is ten more than four times the number of deer caught.

x + y + z = 4 × z + 10

x + y + z = 4z + 10

How many rabbits did Katniss catch?

Number of rabbits = x

We make x subject of the formula

x + y + z = 4z + 10

x = 4z + 10 - y - z

y = 3z

x = 4z + 10 - 3z - z

x = 4z - z - 3z + 10

x = 4z - 4z + 10

x = 0 + 10

x = 10

Therefore, the number of rabbits Katniss caught is 10 rabbits
