Quadrilateral abcd is inscribed in a circle. find the measure of each of the angles of the quadrilateral. show your work.

can someone check my answers? .

m∠c + m∠d = 180°
x - 2 + x - 10 = 180
2x - 12 = 180
2x = 192
x = 96

m∠a = x + 2
m∠a = 96 + 2
m∠a = 98°

m∠b = 96°? ?

m∠c = x - 2
m∠c = 96 - 2
m∠c = 94°

m∠d = x - 10
m∠d = 96 - 10
m∠d = 86°

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
