Question

Given right triangle ABC.



To the nearest tenth of an inch, find the length of side c, the hypotenuse

Answer 1

Use definition of sin, cos, tan to solve this problem.

Answer 2

ok i've tried

Answer 3

You can use the pythagorean theorem. It's easier and it's better to use for this question.

Answer 4

How will he do that he only has one side

Answer 5

any ways look at the angle you know compared to that angle what side is the side you know, opposite, adjacent, or hypotenuse

Answer 6

And also what is the side you want to know

Answer 7

i know opposite but, not hypotenuse

Answer 8

correct, now what trig function involves the opposite and hypotenuse

Answer 9

sine

Answer 10

yep so sin(20)=5/h

Answer 11

what am i supposed to do after that

Answer 12

well rearranging h=5/sin(20)

Answer 13

and finally use your calc to find sin(20)

Answer 14

5/20 right

Answer 15

5/sin(20)

Answer 16

I get 14.6 to the nearest 10th

Answer 17

thanx i've been so stuck

Answer 18

no problem

Answer 19

In order to keep a boat from drifting away, the boat is tied to a pier with a 60-foot rope. When the boat drifts as far from the pier as the rope will allow, the rope forms a 15° angle relative to the horizontal water line.



To the nearest foot, find the maximum horizontal distance, d, that the tied-up boat can drift from the pier
