We have been asked to find the measure of angle JKM. The expression m∠ JKM tells us to find the measure of the angle between rays JK and MK. Let's start by identifying the three angles.
The sum of m∠ JKL and m∠ LKM is equal to m∠ JKM.
m∠ JKL+ m∠ LKM= m∠ JKM
It is also given that m∠ JKL = 15^(∘) and m∠ LKM = 28^(∘). Let's substitute these into the equation.
