Question
What is the central angle of the sector representing hormones enzymes and other proteins?
Options
120°
144°
156°
176°
Solution
144°
Explanation:
The portion representing hormones enzymes and other proteins
= `1 - (1/3 + 1/10 + 1/6)`
= `1 - ((20 + 6 + 10)/60)`
= `1 - 36/60`
= `(60 - 36)/60`
= `2/5`
Central angle of the sector representing hormones enzymes and other proteins
= `2/5 xx 360^circ`
= 144°
