First let's find the mesure of the missing ANGLE: Missing angle = 180° - (42°+ 87°) = 51°
cos 51° = (adjacent side)/(hypotenuse) = x/43
<u />0.629320.91 = x/43
and x = 27.1

<em>C) $46.80</em>
Explanation:
The price of new shoes = $85
The amount paid for the shoes = $ 40
The balance amount for the shoes = $85 - $40 = $ 45
The rate of interest = 8%
The time period = 6 months = 0.5 years
Simple interest:
Simple interest = = $1.8
So, Amount = Principal + Interest
or, Amount = $45 + $1.8 = $ 46.8
<em>The balance amount owned in six months is $46.8</em>
The amount of decrease was 5 -3 = 2 inches,
Percent decrease = 2 /5 = 0.40 x 100 = 40%
