From the diagram given, it can be seen that

The question gives us
mm
Therefore, we can find m
Hence

Thus, m 37°.
Check the picture below.
recall to put the dividend as well as the divisor in descending order, and to include any
missing terms before the constant.
Order of Operations are PEMDAS. So, based on that, the answers would be:
1. 150. Do 20*5 first, as it's in parentheses, then multiply by 10.
2. 36. Same thing as #1 but different numbers.
3. 51. Do the stuff in parentheses first, then multiply because it gets priority over subtraction and then subtract.
4. 16. Do the multiplication in the parentheses first, then the subtraction, and then the division.
