Step-by-step explanation:
117x180°
=21060°
The ratio of a : b : c in its simplest form is 5 : 12 : 30 respectively
<h3>How to solve ratio?</h3>
- a : c = 1 : 6
- b : c = 2 : 5
So,
a / b = 1/6
b/c = 2/5
- lowest common multiple of c in both ratio
1/6 + 2/5
=(5 + 12) /30
a : b and b : c
= 5/30 and 12/30
Therefore,
a : b : c = 5 : 12 : 30
