Question

The point P(15, 20) is on the terminal side of θ. Evaluate sin θ.

Answer 1

help meeeeeeee

Answer 2

Draw a triangle with a length of 15 and a height of 20. Then you can find your hypotenuse and use it to answer your question.

Answer 3

so its 4/5?

Answer 4

Hmmm...looks good.

Answer 5

Good job!

Answer 6

is it not 4/3?

Answer 7

no, 4/3 is the tan.

Answer 8

\[r = \sqrt{225+400}\]=25

Answer 9

so 4/5 is the correct answer?

Answer 10

yes, in reduced form, 20/25=4/5

Answer 11

\[\sin \theta = 20\div25 = 0.8 = 4/5\] and so it seem to be correct
