Answer:
pretty sure C, if not I'm positive its NOT A or B.
Step-by-step explanation:
Answer:
the distance between the penguins and the fish tanks is 81 ft
Step-by-step explanation:
Let A is the point of whales
Let B is the point of Sharks
Let D is the point of Dophines
Let P is the point of penguins
Let F is the point of Fish tank
From a look at the photo, we can find some special properties that:
AB//PF
In triangle ABD and DPF we have
- ∠BAD=∠PFD(Alternate angles)
- ∠ADB=∠PDF(Vertically opposite angles)
By AA rule, ABD and DPF are similar to each other
Therefore, using the similarity property, we have:
= 
So the distance between the penguins and the fish tanks is 81 ft
Answer:
The answer would be B) 120
Step-by-step explanation:
In the triangle with angle 2 and 3, it has a right angle in it, making angle 2 and 3 added together 90 degrees. But you have to figure out what angle 2 and 3 equal. Well the whole triangle is equilateral, making all three angles equal to 60 degrees. Angle 3 is half of 60 degrees because it is split by the dotted line. This makes angle 3 equal to 30 degrees. Now you can find the measure of angle 2. 30(angle 3) plus 90(right angle) equals 120 degrees. This makes angle 2 equal to 60 degrees. In this image, angle 2 is half of angle 1. So angle one is equal to 120 degrees. I hope this helps.
Answer:
Step-by-step explanation:
either x+y=0
∵ if they are on number line and at same distance. then x=-y
or x+y=0
I don’t know I hope you get that though
