Wyatt plays on the school baseball team. In the last 10 games, Wyatt was at bat 45 times and got 21 hits. What is the experimental probability that
Wyatt will get a hit during his next time at bat? Express your answer as a
fraction in simplest form.*

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.
