Question

Triangle ABC is a right triangle with leg lengths of 5 and 12 inches. Find the length of the hypotenuse. Round answer to the nearest hundredth if necessary.

Answer 1

(AB)^2+(BC)^=(AC)^2
5^2+12^2=AC^2
25+144=AC^2
169=AC^2
AC=13inches

Answer 2

You do Sine (SOHCAHTOA).
sin(12)=5/x
Now you have to switch the sin (12) with the denominator (x).
x=5/sin (12)
Then you just divide the equation in your calculator to find x.
Let me know if you need any further help and if you were able to find x.
Also don't forget to round to the nearest degree.
