Okay so there are 45 cheese pizzas and 20 pepperoni pizzas
they are asking for the ratio of cheese pizzas to pepperoni pizzas
that would be 45:20
now this needs to be simplified, so divide both numbers by a common factor, which would be 5 in this case...45/5=9 and 20/5=4
so the ratio would be 9:4
The answer would be 3 and 2. Complementary means when you add two angles together, they equal 90° or a right angle.
You would do 90*2 which is 180 thats the answer 180
You graph it by the y axis and that have a number 1 and you graph it straight sideway
