Answer: 40º
Step-by-step explanation:
To find angle c, not give 2 angles at least, we must use a trigonometric function. With respect to angle c, we can see that we have the opposite and adjacent sides.
The trigonometric function that relates opposite and adjacent sides is tangent.
The measures of angles ADB and BDC add up to the measure of angle ADC:
Then
A. $0.08 per ounce
Price divided by ounces gives you the unit price.
$9.60/120 ounces = $0.08/ounce
The probability that the event won't happen would be .58.
