Question

Find the value of x round the length to the nearest tenth. The diagram is not drawn to scale.

Answer 1

Answer:

$x=2890.1m$

Step-by-step explanation:

From the given figure, it can be seen that AD is parallel to BC, therefore using the alternate angles property, we have

∠DAC=∠BCA=10°

Also, the measure of AB is 500m.

Now, using trigonometry, we have

$sin10^{\circ}=\frac{AB}{AC}$

Substituting the given values, we have

$0.173=\frac{500}{x}$

$x=\frac{500}{0.173}$

$x=2890.1m$

Therefore, the value of x is 2890.2 meters.
