This is a pythagorean theorem problem
When solving for the sides of a right triangle... a^2 + b^2 = c^2
Therefore, 7^2 + b^2 = 25^2
b^2 = 25^2 - 7^2 = 576
b = sqrt(576) = 24
Answer: A 24
Answer:
4 tens
Step-by-step explanation:
3 tens would get you $30, which is $7.80 short. If you give 4 tens you are giving $40 which is 2.20 more than $37.80, which is okay as you can probably get change and it is the least amount of tens you can give to cover the cost.

Hello,
Al 'Kashi theorem says:
a²=4²+7²-2*4*7*cos 20°=12.37721...
==>a=3.518126381...≈3.5 ==>False.
