1. All triangles add up to 180°, so you can make an equation like this:
2. As for which angle corresponds to ∠A, we know that ∠A is across from ∠B which is 60.8°. We know that in the other triangle, ∠Z=60.8° as well and ∠Y is right across from it. Therefore, <u>∠Y corresponds to ∠A</u>.
3. It would be useful to know the options you have for this one. I'd say they're <u>similar</u> (if that's an option).
It is not.You can take the first 4 and times (x) it by 10 and you would get 40. well if you do the same thing but multiply it 10 times greater then the first number (10 x 10= 100) then you take that number (which would be 100) then times it by 4 then you would get 400.
