Question 2

The ratio of the measures of three sides of a triangle is 2:5:4, and its perimeter is 165 units. Find the measure of each side of the triangle. (Hint: the equation is going to be
2x+5x+4x=165)(make sure to plug the value of x back into each to find the final answer)

x = 12, 24units, 60units, 48units

x = 15, 30units, 75units, 60units

x = 15, 45units, 95units, 70units

x = 15, 15units, 30units, 45units
