It can be 2 degrees or 28 degrees.
To find the measure of angle ABD, you can add the measures of angles ABC and CBD since they share a ray. Therefore, the measure of angle ABD is 40° + 23° = 63°. Thus, the measure of angle ABD is 63 degrees.
The idea is that three lines coming out from the center point of a circle (three radii) form three angles -- imagine, for an easy example, the Mercedes-Benz logo. Then the question is: if two of the angles each measure 130 degrees, what does the third angle measure? Well, the first two together measure 260 degrees. So, how many degrees in a circle overall are left, once 260 are taken out? There are 360 degrees in a circle, so the answer is 100.

A parallelogram is a rectangle when all of its angles are right angles (90 degrees). In other words, if the opposite sides of a parallelogram are equal in length and all angles measure 90 degrees, it is a rectangle.

That isn't possible. complementary angles form 90 degrees or a right angle

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.
90 degrees angles or right angles.
Vertical angles are equal in measure and are formed when two lines intersect. Complementary angles, on the other hand, add up to a total of 90 degrees. They are not directly related, but if two lines intersect and form vertical angles, then the angles adjacent to the vertical angles will be complementary.
8 angles of 135 degrees each
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
No - a pair of angles totalling 180 degrees are supplementary. Complementary angles sum to 90 degrees.
