Answer:
$2.67
Step-by-step explanation:
Let the price of a cup of regular coffee be $x. Therefore, the price of a cup of mocha would be $(x+1).
Total price = (3 x $x ) + (4 x $(x+1) ) = $(7x + 4)
7x + 4 = 15.69
7x = 11.69
x = 1.67
Price of one cup of mocha = $1.67 + 1 = $2.67
Answer:
Step-by-step explanation:
The largest angle is opposite to the largest side.
Since the largest side is BC, the largest angle is A.
<u>Work out the angle measure using the law of cosines:</u>
- cos ∠A = (b² + c² - a²)/(2bc)
- cos ∠A = (3² + 7² - 8²)/(2*3*7)
- cos ∠A = -0.14286
- m∠A = arccos (-0.14286)
- m∠A = 98.2°
