I would say it's "A is false, R is true"
Look at it this way, (R is talking): A is false, this is obviously true.
It wouldn't really work the other way.
Answer:
Step-by-step explanation:
The course for a local
triathlon has the shape of a right
triangle. This means that one of the angles formed is 90 degrees.
The legs of the triangle consist
of a 4-mile swim and a 10-mile run. These form the opposite side and that adjacent side of the right angle triangle. The hypotenuse of the triangle is the biking portion of the event. We would determine the length of the hypotenuse by applying Pythagoras theorem. It states that
Hypotenuse ^2 = opposite^2 + adjacent ^2
Hypotenuse ^2 = 4^2 + 10^2 = 16 + 100 = 116
Hypotenuse = √116 = 10.77 miles
Approximately 10.8 miles to the nearest tenth.
