Answer:
Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be
And , because the y-intercept is at (0, R).
So, the equation of this line would be
Where we multiply the equation by
Therefore, the equation that represents this line is
Answer:
The length of shadow is 69 foot.
Step-by-step explanation:
We are given a shadow of lighthouse.
Length of top of lighthouse to end of shadow is 90 ft.
Angle make at top of lighthouse is 50°
Distance from foot of lighthouse to end of shadow is x ft.
we need to find the length of shadow i,e x ft
Using trigonometry ration:
Hence, The length of shadow is 69 foot.
