What are the angle measures of triangle ABC? mA = 30°, m B = 60°, m C = 90°
mA = 90° m B = 60°, m C = 30°
m_A = 60°, m B = 90°, m C = 30°
m_A = 90°, m B = 30°, m_C = 60°

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
