Answer:
So, the distance from boat to matt is 455.81535feet
Step-by-step explanation:
We are given height of a cliff is 305 feet
and the measurement of the angle of depression to a boat on a lake is 42 degrees
so, we can draw diagram
Let's assume
distance from boat to matt is x
We can use trig
[tex]sin(42)=\frac{305}{x}[/tex]
now, we can solve for x
[tex]x=\frac{305}{sin(42)}[/tex]
[tex]x=455.81535feet[/tex]
So, the distance from boat to matt is 455.81535feet
