Answer:
length: 14.2 ft; width 4.2 ft.
Step-by-step explanation:
Let x represent the length of the rectangle in feet. Then x-10 represents the width, and the area is ...
area = length×width
60 = x(x -10) . . . . . substitute the expressions for area, length, width
60 = x² -10x
85 = x² -10x +25 . . . . add (10/2)² to complete the square
85 = (x -5)² . . . . . . . . . rewrite as a square
√85 = x -5 . . . . . . . . . take the square root. Only the positive root is useful for this problem
x = 5 + √85 ≈ 14.2
x-10 = 4.2
The length and width of the rectangle are 14.2 ft and 4.2 ft.

Answer:
8211 miles
Step-by-step explanation:
Delia flew 2416 miles on the first year of the job
She flew 3719 miles on the second year of the job
She flew 2076 miles more than the first and second year combined on the third year
= 2416+3719
= 6135
= 6135+2076
= 8211
Hence Delia flew 8211 miles on the third year
Answer:
Option (2)
Step-by-step explanation:
From the picture attached,
Angle 1 and angle 2 are the angles made between two lines intersecting each other at a point and a third line is perpendicular to one of them.
Therefore, both the angles are equal in measure.
Rest all the options are not applicable to show the relation between these angles.
Option (2) will be the correct option.
