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.
Answer:
D. 
Step-by-step explanation:
Consider the set

This set consists of four ordered pairs.
The first numbers in these pairs are
These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are
These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and

90/ [10(3^2 - 4)]
= 90/ [ 10 (5)]
= 90/ 50
= 9/5
= 1.8
