Question

Angles A and B are complementary angles in a right triangle. The value of csc A is 13/5. What is the value of cot A?

Answer 1

then tan A = 5/12
cot A = 12/5

Answer 2

How did you get 12?

Answer 3

\[12=\sqrt{13^{2}-5^{2}}\]

Answer 4

since the two angles a and b are complementary then the third angle must be 90 degrees

Answer 5

Oh, I see! thanks, that really clears it up.

Answer 6

good luck :)
