Hey there!
Given;
Ratio = 9:8:7
Let "x" be the common factor. So,
9x+8x+7x = 144
or, 24x = 144
or, x = 144/24
or, x= 6
It's like;
= 9*6:8*6:7*6
= 54:48:42
Therefore, their ratio is 54:48:42.

sin 60° = 0.9
Step-by-step explanation:
sin 60° = cos 30°
cos 30° = 0.866025403
0.866025403 to one significant figure
0.866025403 ~ 0.9
~. means approximately.
therefore sin 60° = cos 30°
sin 60° = 0.9
