Given: ac and db are diameters. m∠3=

m∠3 = 78°

From the figure, we have a circle. Also, we have two lines AC and DB being these two lines diameters. A diameter is a line that passes through the center of the circle and touches it in two different points. We also know that m∠1 = 78° and given that  angle 1 and angle 3 are opposite, they measure the same. Therefore m∠3 = m∠1 = 78°

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
