Question

Find the missing angle! Please add an explanation!

Answer 1

The answer is:
`58^\circ`

Explanation:

If we add the angles inside a triangle, we must have
`180^\circ`. So we have an
`57^\circ` angle and an
`65^\circ` angle, their sum is
`122^\circ`, so the missing angle must be
`180^\circ-122^\circ=58^\circ`
