Any two angles of a triangle determine the third angle. As a result, the side angle angle theorem is equivalent to the angle side angle theorem.
what is the formula for a vertical angle
A straight angle is an angle of 180 degrees
The answer depends on which angle is given: whether it is the angle made by the sloping face with the base, or the angle at the apex or even the angle that the sloping face makes with the vertical. Essentially, though, you use Pythagoras's theorem or, equivalently, the sine rule.
The Pythagorean theorem is actually the law of cos, where the angle is 90.

Given two intersecting lines, the two angles opposite each other have the same measure and are congruent.

It is Pythagoras' theorem
exterior angle theorem
An angle of 43 degrees cannot be a vertical angle. A vertical angle, by definition, is 90 degrees

90
No. Or at least, I think not.
