28° and 152°
let the angle be x then supplementary angle = 3x + 68
Supplementary angles sum to 180° , hence
x + 3x + 68 = 180
4x + 68 = 180 ( subtract 68 from both sides )
4x = 112 ( divide both sides by 4 )
x = = 28
the angles are 28° and ( 3 × 28) + 68 = 84 + 68 = 152°
Answer:
The GCF for 84 and 90 is 6.
Step-by-step explanation:
The factors of 84 are: 1, 2, 3, 4, <u>6</u>, 7, 12, 14, 21, 28, 42, 84
The factors of 90 are: 1, 2, 3, 5, <u>6</u>, 9, 10, 15, 18, 30, 45, 90
Then the greatest common factor is 6.
x + y = 7
x - y = 35
and that is your answer
Length is twice the Width
Perimeter = 126 ft.
let width = W
length = 2W
P = 2 length + 2 width
126 ft. = 2(2W) + 2W
126 ft. = 6W
21 ft. = W
width is 21ft., length is 42 ft.
