1) You have:
 Cos(50°)=adjacent/hypotenuse
 Cos(50°)=XY/8
 Solve for XY:
 XY=8Cos(50°)
 XY=8 cm
 The answer is 8 cm

 
2)The angle m∠A is:
 Cos^-1(m∠A)=8/15
 m∠A=57.76°

 The angle m∠C is:
 Sin⁻1(m∠C)=8/15
 m∠C=32.23°

 The approximate difference is:
 m∠A-m∠C≈25.53°

 The answer is: The approximate difference between m∠A and m∠C is 25.53°.

Joy is making a fruit salad. For every 2 cups of blueberries that Joy uses in the fruit salad, she uses 3 cups of strawberries.
Igoryamba

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

Step-by-step explanation:

Given,

Cups of blueberries used for 3 cups of strawberry = 2

Ratio of cups of blueberry to strawberry = 2:3

Joy wants to use 6 cups of blueberries.

Let,

x be the cups of strawberry for 6 cups of blueberries.

Ratio of cups of blueberries to strawberries = 6:x

Using proportion;

Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

2:3::6:x

Product of extreme = Product of mean

2*x=3*6\\2x=18

Dividing both sides by 2

\frac{2x}{2}=\frac{18}{2}\\x=9

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.
