Please help. Brainliest to correct! A blimp can be seen flying at an altitude 4100 feet above a motor Speedway during a race. The slanted distance directly to the pagoda at the start-finish line is d feet. Express the horizontal distance h as a function of d

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
