We first have to find 2 pairs of sides that proportional.

35/20=42/24=7/4

and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.

21/b=7/4

84=7b

b=12

Done!

Hope this helped, any questions about this just ask in the comments and I will answer.

Answer: 13 players.

Step-by-step explanation:

1. Let's call:

$x$ : Price of the shirt ( $x=17$ )

$y$ : Price of socks $y=5.50$

$n$ : number of players.

2. You know that the budget is $300 and you have the following formula given in the problem:

$n(x+y)\leq300$

3. Substitute values and solve for $n$ .Then, you obtain the following result:

$n(17+5.50)\leq300\\22.5n\leq300\\n\leq13.33$

4. The answer is: 13 players.

Which expression can be used to find m pls help

natali 33 [55]

Answer:

∠ U = 22.62°

Step-by-step explanation:

We can use the trigonometric expression to find ∠U by using the ratio:

sin(θ) = opposite/ hypotenuse

=> sin ∠U = 7.5/ 19.5

=> ∠ U = $sin^{-1}$ ( 7.5/ 19.5)

∴ ∠ U = 22.619° ≈ 22.62°
