If you are given 2 of the sides to an obtuse triangle, which trig function should you use to find the other side?

You can only use trig functions on right triangles.

In the diagram above, which of the following is true?

cos(e) = 12 17 \frac{12}{17} 1 7 1 2

sin(e) = 12 17 \frac{12}{17} 1 7 1 2

sin(e) = 17 12 \frac{17}{12} 1 2 1 7

tan(e) = 17 12 \frac{17}{12} 1 2 1 7

Which is true based on the triangle above?

sin(x) = 15 39 \frac{15}{39} 3 9 1 5 ; cos(x) = 36 39 \frac{36}{39} 3 9 3 6 ; tan(x) = 15 36 \frac{15}{36} 3 6 1 5

sin(x) = 15 39 \frac{15}{39} 3 9 1 5 ; cos(x) = 36 39 \frac{36}{39} 3 9 3 6 ; tan(x) = 36 15 \frac{36}{15} 1 5 3 6

sin(x) = 15 39 \frac{15}{39} 3 9 1 5 ; cos (x) = 39 36 \frac{39}{36} 3 6 3 9 ; tan(x) = 36 15 \frac{36}{15} 1 5 3 6

sin(x) = 15 39 \frac{15}{39} 3 9 1 5 ; cos(x) = 39 36 \frac{39}{36} 3 6 3 9 ; tan(x)= 15 36 \frac{15}{36} 3 6 1 5

Using the triangle above, which is true?

sin(C) = \frac{15}{17} 1 7 1 5 ; cos(C) = \frac{8}{17} 1 7 8 ; tan(C) = \frac{15}{8} 8 1 5

sin(C) = 17 15 \frac{17}{15} 1 5 1 7 ; cos(C) = 17 8 \frac{17}{8} 8 1 7 ; tan(C) = 8 15 \frac{8}{15} 1 5 8

sin(C) = 15 17 \frac{15}{17} 1 7 1 5 ; cos(C) = 8 17 \frac{8}{17} 1 7 8 ; tan(C) = 8 15 \frac{8}{15} 1 5 8

Which of the following is true for the triangle above?

sin(A) = 9 15 \frac{9}{15} 1 5 9 ; cos(A) = 12 15 \frac{12}{15} 1 5 1 2 ; tan(A) = 9 12 \frac{9}{12} 1 2 9

sin(A) = 3 5 \frac{3}{5} 5 3 ; cos(A) = 4 5 \frac{4}{5} 5 4 ; tan(A) = 3 4 \frac{3}{4} 4 3
