Answer:
Option 2: 5.34 is the correct answer.
Explanation:
As it can be seen that the given triangle is a right-angled triangle.
Here
Base = 12
Perpendicular = x
θ = 24°
We can use trigonometric ratios to find the value of x. We have to choose a trigonometric ratio which involves base and perpendicular as we only know these two and the angle in the triangle
So,

Rounding off to nearest hundredth
x = 5.34
Hence,
Option 2: 5.34 is the correct answer.
