Question

the measure of the angles of a triangle are in the extended ratio 3 : 5 : 7 what is the measure of the smallest angle?

Answer 1

3:5:7:15
?:?:?:180
by using cross multiplication 3×180÷15=36
the measure of the smallest angle is 36°

Answer 2

Here, sum of ratios = 3 + 5 + 7 = 15
Value of 1 unit = 180 / 15 = 12

So, Ratio measures = 3(12), 5(12), 7(12) = 36, 60, 84

In short, Your Answer would be 36 [ smallest side ]

Hope this helps!
