We have two angles, α and β. we know that -90°< α< β< 90° and that sen(180°+β)> 0. which expression is positive? a)sen α + sen β b)cos α - cos β c)cos α - tan β d) - cos β - tan β can someone show the solution step by step?

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

3
