Step-by-step explanation: These can all be solved using vertical angles, complimentary angle theorem, and supplementary angle theorem! Really fancy names to say that opposite angles are equal, vertical angles (like #5). Two angles that add up to 180 degrees forming a straight line, complimentary angles (like in #1). And in a right angle two angles will always add up to 90 degrees (#7 for example). 10 11 and 12 require you to use vertical angles and complimentary angles to solve them.
It must be an equation in order to be solved for example, 3x+5=11 then x would be 2
The answer is 17/5. You have to take the whole number, multiply that by the denominator. Then add that number to the numerator to get the new numerator and the denominator stays the same as before (5)
The answer is B :)
Have a nice day
