Question

how to find out the largest angle according to their ratios

Answer 1

Heya...

The largest number in the ration refers to the largest angle..

For example, 1 : 2 is a ratio of two angles... And given these are complementary angles...

Hence..

1x + 2x = 90

3x = 90

x = 90 / 3

x = 30

Therefore... the first angle is 30` and the second angle is 60`

Hope it satisfies u...

Answer 2

You can use the Law of Sines to find the ratio of the sines of your two angles:

a/sinA=b/sinB=c/sinC=D
