Answer:
Distance covered by the boat was 446.27 feet
Step-by-step explanation:
A boat which is at the point C approaching the light house.
At point C angle of depression to the boat was 17°44' and when boat stops at point B angle of depression was 48°13'.
Length of the tower is 200 feet then distance DC traveled by the boat.
Since at point B angle of depression was 17°44' so we will convert the angle in degrees.
Angle of depression = ∠ACB = 17°44' = 
From ΔABC
tan 17.73° = 
Now in ΔABD
∠ADB = 48°13' = 48° + 
= 48.217°
Now 
Therefore distance DC = BC - BD
DC = 625 - 178.73 = 446.27 feet
So the answer is 446.27 feet was distance covered by the boat.

Step-by-step explanation:
In the triangle XY and XZ are tangent to circle C. This means that the length has of XY and XZ are congruent.
So first you have to set the equations to each other to find what b equals to.
85b+83=91b-283
Add 283 to both sides
85b+366=91b
Subtract 85b on both sides
366=6b
Divide by 6
B=61.
Then you substitute 61 as b in the equation for XY.
85b+83
85(61)+83
5185+83
5268
In this question, you're trying to transform the equation into slope intercept form.
Slope intercept form equation:
y = mx + b
In this case, you would need to get the "y" variable by itself.
To do so, you would subtract -2x from both sides:
2x + y = 2
y = -2x + 2
Answer:
y = -2x + 2
