The multiples of 7. Answer: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, <span>98, 105, 112, 119, 126, 133, 140, 147, 154, 161, 168, and more </span> These are all factors of 28. Let's list out the factors of 28: 1, 2, 4, 7, 14, 28. Each of the numbers in this list are factor pairs. We can move from the outsides to the center and pair the numbers together to make sets of numbers that will multiply to make 28.
Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.
Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:
<a and <b,
<c and <d.
Thus, <a is congruent to <b, and <c is congruent to <d.
Therefore, the standby that is true about vertical angles is that:
This is a 45-45-90 triangle or a right triangle created by the sides.
Because of this being a right triangle and 45 degrees being given already for one angle you would add 90 and 45 which will give you 135. You would subtract 135 from 180 because all the angles of a triangle add up to 180°. 180-135=45. X=45°
