<h3><em>The distance from the lighthouse to the boat will be given by:
</em></h3><h3><em>tan θ=opposite/adjacent

</em></h3><h3><em>opposite= height of the lighthouse

There is no work. i just did it in my head. x = 15 because 15^2 equals 225 and 15+2 = 17 so if 15*15 equals 225 then if you add 30 more that is 255. 30 is equal 2*15 and so you could also say 15*15+(15*2) so 15*17 = 255 so x = 15. you're welcome.
Answer:
x=2
Step-by-step explanation:
4x=8
4x/4= 8/4 Divide both side by four to find x
8/4= 2 which equals x
1:3 is the ratio because if 1/4 are green then 3/4 are orange
13. x= 27/4 or 6 and 3/4
14. x= 27
15. x= 191/7 or 27 and 2/7
16. x= 83/15 or 5 8/15
the key to solving these is cross-multiplying and finding a common denominator, you can use photomath if you want to see the solving steps, hope this helps!
