harina [27]

Answer:

cscA = $\frac{5}{4}$

Step-by-step explanation:

Using the identity

csc x = $\frac{1}{sinx}$ , then

sinA = $\frac{opposite}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{8}{10}$ = $\frac{4}{5}$ , thus

cscA = $\frac{1}{\frac{4}{5} }$ = $\frac{5}{4}$

Elina [12.6K]

Answer:

<u>30 gallons solution 4% and 10 gallons solution 8%</u>
