I believe the answer is 6
Only because I see that I can divide 3 and 2 and I know that the answer is 6
The answer is c first 2×6= 12 then 12-5=7
then do -7×-2=14 the minus signs cancel
finaly we have two bracket so we multiply both number (7)×(14)=98
Related angle is 45 degrees, set up a triangle and use exact trig values to solve for x and y, then rationalise the denominators
