Line l and line m are straight lines. Which statements are true regarding the angles in the figure? Select two options. Measure of angle a = measure of angle b Measure of angle a = measure of angle c Measure of angle a + measure of angle b = measure of angle c Measure of angle a + measure of angle b = 90 degrees Measure of angle a + measure of angle b + measure of angle c = 124 degrees
