Answer:
c ≈ 40
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
= 
( multiply both sides by c )
c × sin40° = 26 ( divide both sides by sin40° )
c = 
≈ 40 ( to the nearest whole number )

Answer:
Selling price of the XBOX 360 = $319.20
Step-by-step explanation:
Given that an XBOX 360 regularly sells for $399.
That means marked price of an XBOX 360 = $399
Now we need to find about what is the sale price of the XBOX 360.
Given that it is on sale for 20% off.
Then discount = 20% of $399 = 0.20 (399)= $79.80
Then selling price of the XBOX 360 = (marked price) - (discount)
=399 - 79.80
= $319.20
