It is true because if a is perpendicular to b and b is perpendicular to c therefore a has to be perpendicular to c also they said that all three lines are coplanar therefore the statement must be true

I hope this helped you out :)

Using the law of sines, it is found that the distance between the kite and the dog is of 284.77 meters.

<h3>What is the law of sines?</h3>

Suppose we have a triangle in which:

The length of the side opposite to angle A is a.

The length of the side opposite to angle B is b.

The length of the side opposite to angle C is c.

The lengths and the sine of the angles are related as follows:

$\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}$

For the situation described, we have that:

The height is opposite to the angle of 42º.

The 425 meters are opposite to the angle of 87º.

Hence:

$\frac{\sin{42^\circ}}{h} = \frac{\sin{87^\circ}}{425}$

Applying cross multiplication:

$h = 425\frac{\sin{42^\circ}}{\sin{87^\circ}}$

h = 284.77 meters.
