so how to ask it?

ok? 

maybe but i don't care

you can look at the question right after this, he/she ask the same question. :) but a quick explanation, it is basically the learning of angles and slides. the basic trigonometry only uses the right triangle, also you need to know a^2+b^2=c^2 and sin=opposite/hypotenuse  cos=adjacent/hypotenuse and tan=opposite/hypotenuse, I hope that help. :)

yes it dose thx

because if it is a number you must type you can't copy and past numbers. sorry 

1.25p=15, then we divide 1.25 on both sides to get 12 then our answer would be 12. p=12

none(if y=0) since we use the quadratic equation and we use a calculator we got our answer :D

thanks for the help guys

we use the distant formula to found out that the diameter is 4 then we divide it by 2 and found out that the radius is 2 the area of this circle is 4\( \pi\)
