Two angles are supplementary when they <span>add up to 180 degrees.
x = angle
19x-60 = </span><span>supplement angle
x + 19x - 60 = 180
20x = 180 + 60
20x = 240
x = 240/20
x = 12</span>° ← answer
10.85 miles / 1.4 hrs = 7.74 miles per hour
Use the quadratic formula to solve. the answer is the third one down
x= -sqrt10 - 4 and sqrt10 - 4
or in their notation above x= -4+/-10--sqrt

Answer:
The formula to determine the length of rectangle with perimeter and width is L =
Step-by-step explanation:
Given as :
The perimeter of rectangle = P
The length of rectangle = L
The width of rectangle = W
∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width
I.e P = 2 L + 2 W
Or, 2 L = P - 2 W
∴ L =
Hence The formula to determine the length of rectangle with perimeter and width is L =
