If angle ABC measures 70 degrees, what does angle ADC measure

Please consider the complete question.

We can see from attached file that angle ABC is central of circle B that corresponds to arc AC. We can also see that angle ADC is inscribed angle of circle B and corresponds to arc AC.

We know measure of an inscribed angle is half the measure of central angle, when both subtends to same arc.

Therefore, the measure of angle ADC is 35 degrees.

you just switch the numbers basically so it would be 3/17

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
