Application +4 | -1
If the sines of the angles of a triangle are in the ratio 4:5:64: 5: 6, then their cosines are in the ratio
View answer and explanation
Correct option: B
12:9:212: 9: 2
Option B (12: 9: 2) is correct because using the cosine rule and the sine rule, the ratio of cosines can be found to be 12:9:2.
