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 side.

T a n 29 ° = 91 x Tan\ 29\degree\ =\ \frac{91}{x} T a n 2 9 ° = x 9 1

S i n 29 ° = x 91 Sin\ 29\degree=\frac{x}{91} S i n 2 9 ° = 9 1 x

C o s 29 ° = x 91 Cos\ 29\degree\ =\ \frac{x}{91} C o s 2 9 ° = 9 1 x

T a n 29 ° = x 91 Tan\ 29\degree=\ \frac{x}{91} T a n 2 9 ° = 9 1 x

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
