1.) The length of the missing side is?
2.) What is the length of the missing side?
2 answers:
To find the hypotenuse the formula would be: c^2 = a^2 + b^2 BUT! These two questions ask for the length of the smaller sides, so we need to rearrange the formula to: a^2 = c^2 - b^2 Where c is the hypotenuse, and b is the other known length. Use this formula to solve the length of the unknown side. Let's call the unknown side x, 1) a^2 = c^2 - b^2 x^2 = 17^2 - 15^2 x^2 = 64 Square root both sides to get x x = 8 2) a^2 = c^2 - b^2 x^2 = 26^2 - 24^2 x^2 = 100 Square root both sides to get x x = 10 Hope this helped! Ask me if there's any part of the working you don't understand :)
A^2 + b^2 = c^2 a^2 + 15^2 = 17^2 a^2 + 225 = 289 a^2 = 289 - 225 a^2 = 64 sqrt of 64 = 8 a = 8 x = 8

Hope it's right if not so sorry : )
Hmm, I am pretty sure the answer is A.
This would be C. 60$
This is because if she got the bag for 50% off, 30 divided by 2 is 15$, 45 divided by 2 is 22.5, 60 divided by 2 is 30$ so option C. Would be your answer.
30.5/5= 6.1 yards per ribbon
The answer to the variable b is 708.4
