Answer:
C
Step-by-step explanation:
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:
using cosine rule:
0.09/10=0.009
we check it: 0.009*10=0.09, so it's right
Divide the number of events by the number of possible outcomes
