Answer:
C. 5/12
Step-by-step explanation:
Finding the missing side :
- Opposite side² + Adjacent side² = Hypotenuse²
- (5)² + Adjacent side² = (13)²
- Adjacent side² = 169 - 25
- Adjacent side² = 144
- Adjacent side = √144
- Adjacent side = 12
Taking the tan ratio :
- tanθ = opposite side / adjacent side
- tanθ = 5/12
