Answer:
6$ is the correct answer have a good day :)
I assume that you want the measurement of angle A
A + (A + 38) = 90
angle A + (38 more than angle a) = are complementary
2A = 52
A = 26
Hope this helps. If it did, consider making it Brainliest!
14.25+2.30=16.55 so, dr spent $16.55 on school supplies
We can't tell. We need to know how the angles N and L are related.
(Scroll to the bottom to see my answer) The order of operations is PEMDAS aka Parentheses. Exponents. Multiplication or Division (Which ever come first). Addition or Subtraction (again whichever comes first). Start with (12-9)=3 then multiply 3 by 3, three times=9 then multiply 2 and 7 together=14 then do 9-14=-5
So my final answer is -5! I might be wrong but I did my best! I hope I’m not too late!
