Answer 1

Answer 2

You'll need to first find the value of r using the Pythagorean theorem.

10^2 = 8^2 + r^2. If you know the Pythagorean triples, you may be able to get the value of r by inspection. Otherwise, crank it out as in the previous problem.

Answer 3

100=r^2+64

Answer 4

Subtract 64 from both sides.

Answer 5

36=r^2

Answer 6

6=r^2

Answer 7

so 4/3? huh

Answer 8

No. Squaring a number and dividing a number by 2 are different operations.

36=r^2

What is the square root of 36?

Answer 9

6

Answer 10

ok. Now, the definition of the contangent ratio in a right triangle.

Answer 11

got it..

Answer 12

cot(R) = adjacent leg length divided by opposite leg length

cot(R) = 8/6 = ? when reduced. @cutegirl

Answer 13

4/3

Answer 14

Yes. That is what I got.
