The answer is A.
USE PYTHAGOREAN THEOREM
3^2+6^2=c^2
9+36=c^2
45=c^2
c=3 sqrt5
Answer:
Bicycles = 315
Scooters = 630, basic mathematics. The most effective method for these questions is substitution. But I might have intermingled them so double check
Since 25% is 1/4 divide 28 by 4 to get your answer of 9.5
There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.
