Radius is 12.0 cm. Radius is half of the diameter, so I'm just going to guess that 24 cm is the diameter. Anyways half of that is 12.
If MO bisects the angle, then angle LMO= angle NMO. So,
7x-12 = 2x+38
Now, take the x variable on the same side and the constants on the same,
7x-2x = 38+12
5x = 50
Divide by 5 on both sides,
x = 10
A stem and leaf plot is called a stem and leaf plot because it is a table where each number in a set gets broken up into stems and leaves.
Stem = the first digit, or digits
Leaf = the last digit
Ex: The stem of 32 would be 3 and the leaf would be 2.
