<h3>What is a scalene triangle?</h3>
A scalene triangle is a plane figure that has 3 different length sides and 3 different angles. The sum of all the angles in a scalene triangle is equal to 180°
i.e
- Let's assume that angle y = 60° and angle z = 50°
Then;
x + 110° =180°
x = 180° - 110°
x = 70°

Answer:
The number of men = 108
Step-by-step explanation:
Total person = 396
ratio of women to men = 2:3
ratio of men to children = 1:2=2:4=3:6
Women = 2
Men = 3
Children = 6
Hence,
women+men+children = 2+3+6 = 11
Now finding out the percentage of each
Women = 2/11 * 396
= 792/11
=72
Men = 3/11 * 396
=1188/11
=108
Children = 6/11 *396
=2376/11
=216
Thus the number of men = 108 ....
