Question 1090735
if a pair of supplementary angles are in the ratio 4 is to 5 ,then help me to find the smaller angle
<pre>Smaller angle has smaller ratio-value out of a total of 4 + 5, or 9 parts.
So, smaller angle = {{{highlight_green(matrix(1,5, (4/(4 + 5)) * 180, "=", (4/9) * 180, "=", 80^o))}}}
