Answer:

x = 36.27

Step-by-step explanation:

By using the steps to find sin θ backwards, we can find x, the hypotenuse.

sin θ = \frac{opposite}{hypotenuse} or side \frac{a}{c} (as seen in my example picture).

We already know the value for sin (α), which is 32° because its given. The opposite side (a) is 20 and the hypotenuse side (c) is x which are both also given.

So the equation now looks like:

sin 32° = \frac{20}{x}

Don't solve for the sin 32 yet! First, we have to isolate the variable.

To get rid of the x in the denominator you have to multiply both sides by x:

( sin 32 ) · x = ( \frac{20}{x} ) · x

( sin 32 ) x = 20

Then, you have to divide both sides by sin 32 to get x by itself:

(( sin 32 ) x ) ÷ ( sin 32 ) = 20 ÷ ( sin 32 )

x = 20 ÷ ( sin 32 )

Lastly, you have to use a calculator to find 20 ÷ ( sin 32 ), and it should give you 36.2695543766.

The question asks you to round to 2 decimal places so:

x = 36.27

A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. From this sugar mixture, set aside 1/4 cu
ch4aika [34]

brown sugar= \frac{3}{8}

white sugar= \frac{1}{3}

you need to mix brown sugar with white sugar

\frac{3}{8} + \frac{1}{3} = \frac{9+8}{24} = \frac{17}{24}

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was  \frac{17}{24}, so

\frac{17}{24} - \frac{1}{4} = \frac{68-24}{96} = \frac{11}{24}

The sugar mixture used to make the cake is \frac{11}{24}
