First You would divide both numbers by ten to get 15 and 25. Then you realize that both numbers are divisible by 5 so you divide both sides you then end up with 3 to 5 which is your answer.
Answer:
we need the picture. we cant do this without the picture
Step-by-step explanation:
The answer is 145 divided by tan 65 degrees.
Since the equation for tangent is opposite/adjacent, you can just plug the numbers in.
tan(65)=145/x (x being the height that you are trying to find)
tan(65) * x = 145
Then divide tan(65) to isolate the x and you get:
145/tan(65)
Hope this helps!
Sorry, don't have time to do them right now but I know who does!
