ANSWER
The exact value is 24√3
The approximate value is 41.6 to the nearest tenth.
x=52.1 units.
EXPLANATION
Let the blue dotted line be h units.
This line is opposite to the 60° angle.
The side length of the triangle which is 24 units is adjacent to the 60° angle.
So we use the tangent ratio,
This is the exact value.
This is that approximate value to the nearest tenth.
To find the side length , x, we need to use the second triangle.
