Vertically opposite angles are the angles that are formed when two lines intersect. When the lines cross, they create two pairs of opposite angles that are equal in measure. For example, if two lines intersect and form angles of 40 degrees and 140 degrees, the angles across from each other (the vertically opposite angles) will both be 40 degrees and 140 degrees, respectively. This property is a fundamental concept in geometry.

The ratio of the opposite side over the adjacent side is called the tangent.Expressing the fraction (opposite/adjacent) as a decimal, you can find the angle by looking in a table of values for the tangents of various angles.
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
You would have to use its opposite tangent, tan-1on your scientific calculator. It would be tan-1(opposite side/adjacent side), and you must have the opposite and adjacent sides of the angle you are trying to solve.

To answer a vertically opposite angle question, first identify the intersecting lines forming the angles in question. Vertically opposite angles are the angles that are opposite each other when two lines cross. Since vertically opposite angles are always equal, you can simply state that the angles are equal and provide their measures if known. If specific angle measures are given, set them equal to each other to solve for any unknowns.
Vertically opposite angles!
Such angles are called vertically opposite angles.
Vertically opposite angles are the angles that are opposite each other when two lines cross. Vertical means they share the same vertex.
A complementary angle is an angle that when added to another angle creates a 90o angle. A supplementary angle is an angle that when added to another angle creates a 180o angle.
