Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
Answer:
1 : 1740
Step-by-step explanation:
The piece paper has 8 1/2" x 11", we have must find the appropriate dimensions on a scale such that the drawing of the Empire State is contained within the measures of the piece of paper. Leaving a margin of 1/2 "on both sides we have 10" high by 7 1/2" wide.
we choose the highest side of the piece of paper (11 "including margin 10") to cover the height and width (8 1/2 "including margin 7 1/2") for the base
.
1450 ft ≅ 10"(inch) then:
400 ft ≅ x "(inch); x=400ft*10"/1450ft ⇒ x=2.75", also
the scale is:
if 1450 ft ≅ 17400" ⇒ 17400" in the reality are 10" in the piece of paper, so the relation is 1 : 1740, is to say, 1" in the piece of paper is 1740" in the reality
Note: but wish to leave room, the scale can be 1 to more than 1740
Is it because the second discount will be determined by the first discounted price, $405, not $450.

Answer:
23 inches
Step-by-step explanation:
If we add 5 inches to the shortest side, all sides will be the same length and the perimeter will be 69 inches. The longest sides have length that is 1/3 that, or ...
... (1/3)·(64 +5 in) = 23 in
_____
You can solve for x, but you obviously don't need to.
The perimeter is ...
... (4x -2) + 2(4x -2 +5) = 64
... 12x +4 = 64
... 12x = 60
... x = 5
... 4x -2 +5 = 4·5 +3 = 23 . . . . the length of the longest side in inches
