Answer:
x = 109
Top Right Angle = 109
Bottom Right Angle = 71
Step-by-step explanation:
Notice the two right angles on the left and recognize that the figure is a a quadrilateral (4 sides). That means it adds up to a total of 360 degrees.
(x-38) + x + 90 + 90 = 360
2x + 142 = 360
2x = 218
x = 109
(x - 38) = (109 - 38)
71 degrees for bottom right angle
109 for top right angle

Answer:
75
Step-by-step explanation:
322 = 2(86) + 2w
322 = 172 + 2w
322-172 = 172 +2w -172
150 = 2w
150/2 = 2w/2
w=75
Hello! 12 make a dozen. 12 * 6 is 72. 72 cookies make 6 dozen. 2 cups of sugar are needed to make 6 dozen. 36 cookies is 3 dozen, because 3 * 12 is 36. 36 is ½ of 72, so we would need ½ of the amount of sugar needed for 6 dozen cookies for 3 dozen cookies. ½ of 2 is 1. There. 1 cup of sugar is needed to make 3 dozen cookies.
