Step-by-step explanation:

Let

Y ----> field of vision that Yash's camera would need

we know that

Applying the law of sines

$\frac{sin(Y)}{25}=\frac{sin(41\°)}{30}$

Solve for sin(Y)

$sin(Y)=\frac{sin(41\°)}{30}(25)$

$Y=sin^{-1}[\frac{sin(41\°)}{30}(25)]$

$Y=33.14\°$

Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?

NemiM [27]

Answer:

3/4 of a foot will cost $2.25.

Step-by-step explanation:

This question is solved by rule of three, due to proportions.

One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?

1 foot - 3 dollars

3/4 foot - x dollars

$x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25$

3/4 of a foot will cost $2.25.
