Question:

A triangle has one right angle, what is the value of the other two angles combined? The two legs of the triangle equal 7 and 24, what is the length of the last side?

Grace C.
Answer:

Since all the angles in a triangle add up to 180, 180-90 = 90. You could solve this in 2 ways. First, $$ 7^{2}$$ + $$ 24^{2}$$ = $$ c^{2} $$. c = 25 Or, by using special right triangles, one could determine that the last side will be 25 due to the 7-24-25 triangle.

Question:

Cindy and John each collect apples from a farm to sell. When they combine their apples, they have 24 apples, but John collected 4 more apples than Cindy. How many apples did John collect? How many apples did Cindy collect? If they sold all 24 apples for 50 cents each, how much money do they make?

Grace C.
Answer:

24 - 4 = 20 (If they each collected the same) $$ \frac{20}{2} $$ = 10 (without John's additional 4, they each collected 10) 10 + 4 = 14 (Include John's extra 4) John collected 14 apples while Cindy collected 10 apples. 24 apples x $0.50 = $12!
