Answer:
perimeter = 25.13feets
Step-by-step explanation:
width = 25/6 feet
Area = 35 square feet
lenght = Area/width = (35*6)/25 = 8.4feets
perimeter of the rectangle = 2(25/6 + 8.4) = 25.13 feets
Answer:
n=3.5 a=1.41 units a'=4.95 units b3 units b'10.5 units c2.24 units c'=7.83 units
Step-by-step explanation:
This answer assumes that n = 3.5. The ratio of each side length on to the corresponding side length on is equal to 3.5. For example, a′ = 3.5a. The ratio is equal to the scale factor, n.
Because this is 4 sided, it is 360°(in total)
The shape is parallel on 2 sides(shown by the red arrows), so (5x)° = 90°
5x = 90
x = 18°
You can add all the angles together and set it equal to 360°
90° + (5x)° + (5(y+11))° + (4y-10)° = 360°
Since you know 5x is 90°, you can plug it in
90° + 90° + (5(y+11))° + (4y-10)° = 360°
180° + (5(y+11))° + (4y-10)° = 360° Subtract 180° on both sides
(5(y+11))° + (4y-10)° = 180°
5y + 55° + 4y - 10° = 180°
9y + 45° = 180°
9y = 135°
y = 15°
x = 18°, y = 15°
