Angles JHI and GJH are inscribed angles. We have that m∠JHI = b and m∠GJH = a by the. Angle JHI is an exterior angle of triangle. Because the measure of an exterior angle is equal to the sum of the measures of the remote interior angles, m∠JHI = m∠JGI + m∠GJH. By the, b = m∠JGI + a. Using the subtraction property, m∠JGI = b - a. Therefore, m∠JGI = (b - a) by the distributive property.
