Answer:

sin α = 12/37

apply Pythagoras theorem,

Let get unknown side =y

12^2 + y^2 = 37^2

y^2 = 37^2 -12^2

y^2 = 1225

y = sqrt(1225)

y = 35

so, cos α = 35/37

Step-by-step explanation:
sin = y/z = 12/37

tan = y/x
*find the x*
x = root 37^2 - 12^2
x = root 1369 - 144
x = 1225
x = 35

tan0 = 12/35
