Answer:
80°
Step-by-step explanation:
The sum of the angles of any triangle must add up to 180°. If you form a triangle with an angle of 40° and another angle of 60°, the sum of those two angles is 40 + 60 = 100, so the measure of the third angle: 180 - 100 = 80°.

Answer:
60 feet of fencing
Step-by-step explanation:
Let x feet be the width of the garden plot, then 2x feet is the length of the garden plot.
The area of the garden plot is
Find the perimeter of the rectangular garden plot:
32.75 + 39.88 = 72.63
72.63 x 114% = 72.63 x 1.14 = $82.7982 or $82.80 to the nearest cent.
114% is all of the cost of the meal plus 14 % extra for the tip. See how muliplying by 1.14 includes the $72.63 (this saves the step of adding it on at the end if you were only to find 14% of $72.63)
