for the length use Pythagoras
First multiply the original price by the discount. (250.99 x .78 = 195.7722)
Then subtract that number from the original. (259.99 - 195.7722 = 55.2178)
Then round to 2 decimals because dealing with money.
Answer: $55.22
I guess he needs to save $4 more to buy the shoes
Angles in a triangle must add up to 180, so the missing angle inside the triangle is 180 - (70 + 40), which is 70.
Angles on a straight line (i.e. the line BD) must add up to 180, and because we know part of that angle is 70, x must be 180 - 70, which is 110.
Hence, x is 110 degrees.
