Complementary-angles that add up to 90 degrees
Supplementary-angles that add up to 180 degrees
Linear pair-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. (You could shorten that if you’d like)
Adjacent-Two angles that have a common side and a common vertex (corner point), and don't overlap
Congruent-angles that are equal
Parallel lines-side by side lines that will never touch

I don’t have time to finish the rest but I hope this helps

How many grams are there in 3.3 x 10^23 atoms of boron?

iren [92.7K]

5.924 g

Step-by-step explanation:

The average weight of a boron atom is 10.811 atomic mass units (AMU). Therefore 3.3 x 10^23 atoms of boron will weight;

3.3 x 10^23 * 10.811 = 3.56763 x 10 ^ 24
