You want to slpit 90 degrees in the ratio 2:3 ?

Awesome so what is a ratio? It gives us the value for which something would be divided. So here they want you to answer in the form of ratios.. 2:3 means 2 parts and 3 parts of 90' Let us say that they wanted to divide 10doughnuts in the ratio 2:3 Then it would be divided as 4:6 [The whole is 10] which is = 2:3 Getting it? :)

Now they want you to divide 90 into 2prts and 3 parts of the whole. Well how do we do that? If a ratio is ever given to you... The actual value of the parts would be given by a common term multiplied to the ratio. For example here: 2:3 means 4:6 [Whole: 10] means 8:12 [Whole: 20] means 16: 24 [Whole: 40] So above everything is actually = 2:3

Let the common term multiplied to 2:3 in our question be x So 2x:3x is the actual ration of the angles. 2x + 3x gives us the whole = 90 5x = 90 x = 18' So the common term that we multiply to the ratio 2:3 to get the actual value of the angles is 18' So the angles = 2*18 and 3*18 = 36 and 54 which ultimately result in the ratio 36:54 = 2:3 in the simplifies manner and add upto 90. So we divided 90 into 2 parts of 36 and 54 in the ratio 2:3. Understood? :)
