Answer:
Step-by-step explanation:
So first we notice that the traingles are similar which makes my work much easier.
27:42 can be simplified to 9:14.
That means x is 28
And sharks to dolphins is 12.
That means the smaller triangle is 27 18 12 and the bigger triangle is 42 28 and x. Try and do it yourself if you can't just comment and I'll help you :)

Answer:
b-65
Step-by-step explanation:
They give you 130 and so to get the next measure its 180-130 and you get 50. So the blank angle is 50. Then the next two angles are y which means theyre equal to each other so they have to be the same number. Get 180 again and subtract 50 and get 130. Split 130 in half and get 65.
6 feet:10 hours
multiply by 1.5 on both sides
9 feet:15 hours
answer: 9 ft
