b) Scalene Acute

Step-by-step explanation:

b) Scalene Acute

A scalene triangle is a triangle with none of its sides equal to each other. Here, The sides MN,NO,OM with their respective values of 4.94,4.65.3.65 are not equal. Hence, Scalene.

An acute triangle is a triangle in which the largest angle of the triangle is more than 90 degree. Here, Neither  63, 45 nor 72 are greater than 90 degrees.

Hence, Acute

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
