What leg is considered the hypotenuse?

the side opposite the right angle

the side opposite the smallest angle

the side opposite the shortest leg

Identify the trig ratio that may be used to find the marked unknown side.

S i n 38 ° = h 15 Sin\ 38\degree\ =\ \frac{h}{15} S i n 3 8 ° = 1 5 h

S i n 38 ° = 15 h Sin\ 38\degree\ =\ \frac{15}{h} S i n 3 8 ° = h 1 5

C o s 38 ° = 15 h Cos\ 38\degree\ =\ \frac{15}{h} C o s 3 8 ° = h 1 5

T a n 38 ° = h 15 Tan\ 38\degree=\ \frac{h}{15} T a n 3 8 ° = 1 5 h

Identify the trig ratio that may be used to find the marked unknown angle.

T a n y ° = 12 18 Tan\ y\degree=\ \frac{12}{18} T a n y ° = 1 8 1 2

S i n y ° = 12 18 Sin\ y\degree=\frac{12}{18} S i n y ° = 1 8 1 2

C o s y ° = 18 12 Cos\ y\degree\ =\ \frac{18}{12} C o s y ° = 1 2 1 8

C o s y ° = 12 18 Cos\ y\degree\ =\ \frac{12}{18} C o s y ° = 1 8 1 2

Identify the trig ratio that may be used to find the marked unknown side.

C o s 38 ° = 15 w Cos\ 38\degree\ =\ \frac{15}{w} C o s 3 8 ° = w 1 5

S i n 38 ° = w 15 Sin\ 38\degree=\frac{w}{15} S i n 3 8 ° = 1 5 w

T a n 38 ° = w 15 Tan\ 38\degree\ =\ \frac{w}{15} T a n 3 8 ° = 1 5 w

S i n 38 ° = 15 w Sin\ 38\degree=\ \frac{15}{w} S i n 3 8 ° = w 1 5

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.
