Using relations in a right triangle, it is found that
The relations in a right triangle are given as follows:
In this problem, the situation is modeled by the graph given.
First, we have to remember that the sum of the internal angles of a triangle is of 180º, hence:
The angle formed at Maria's position measures 50 degrees.
Then, for the distance from Maria to Ava, which is the hypotenuse:
[tex]\sin{50^\circ} = \frac{12}{h}[/tex]
[tex]h = \frac{12}{\sin{50^\circ}}[/tex]
[tex]h = 15.66[/tex]
Hence:
The distance from Maria to Ava is 15.66 feet.
Finally, for the distance from Lucas to Maria:
[tex]\sin{40^{\circ}} = \frac{d}{15.66}[/tex]
[tex]d = 15.66\sin{40^{\circ}} = 10.07[/tex]
The distance from Lucas to Maria is 10.07 feet.
