Can you use a calculator? If yes, then isolate 7) cot 8) tan 2 theta, etc. Then, input the inverse of that trig into the calculator. 

Ex. #7 cot theta= -6/5
Then, input arccot (-6/5) (aka inverse cot (-6/5)) into your calculator.

Insert parentheses to make each statement to make each statement true 6×7+2-1=53
Alexus [3.1K]
The correct answer is 6 × (7 + 2) - 1 = 53. This is because in the Order of Operations, multiplying comes first. So to make sure you get the right answer, you have to put the 7 + 2 in parentheses to get 6 × 9 - 1 and not 6 × 7 + 1.
