If one angle of a triangle has a greater measure than another angle, then the side opposite the greater angle is longer than the side opposite the lesser angle.
With that being understood, let's now take a closer look at the given diagram.
We can see that ∠ MSR is opposite to MR and ∠ MRS is opposite to SM. However, the diagram does not show a measure for ∠ MSR. To find this measure, notice that ∠ VSM and ∠ MSR form a linear pair. The sum of their measures is 180^(∘).
m∠ VSM + m∠ MSR =180^(∘)
From the diagram, we know that ∠ VSM measures 110^(∘). Let's substitute this value into this equation and calculate the measure of ∠ MSR.
