So basically I clicked on some thing and got a virus on my phone like this random number popped up and every time I try to call or click cancel nothing happens it’s come back up again and it won’t let me click on anything else—I know this app is for school I use it for school too but I’m out of options and there’s some very important things on this device

i hope im right but have u tried restarting your phone or getting it checked out?

Step-by-step explanation:

Coterminal angles are angles with the same terminal side.

When we have an angle A, the coterminal angles can be written as:

A + k*(360°)

where k can be any integer number. (Notice that when we have k = 0, means that A is coterminal with itself)

Then the set of all the coterminal angles to -225° is:

{-225° + k*360°I k ∈ Z}

where Z is the set of integer numbers.
