Answer:
Great question! The simple way to solve this is using a formula you may already know of from your teacher. It's called the pythagorean theorem!
What's the formula then, huh?
a² + b²= c²
c² is your hypotenuse, or the diagonal angle.
Plug it in!
12.75² + 17² = c²
Square the numbers!
162.5625 + 289 = c²
Add your numbers together!
162.5625 + 289 = c²
Now square root (√) both sides in order to get rid of the c²
454.5625 = c²
Final Answer:
c = 21.25 (D)
