For a clearer answer look at the image.
Step-by-step explanation:
10² + 10² = 10^4
5.84 + 2.85 = 8.69
8.69 × 10^4
Answer:
80 ft x 40 ft
Step-by-step explanation:
Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).
The equations that compose the linear system are:
![L+2W=160\\L=2W](https://tex.z-dn.net/?f=L%2B2W%3D160%5C%5CL%3D2W)
Solving the system:
![L+L=160\\L=80\\W=\frac{L}{2}\\W=40](https://tex.z-dn.net/?f=L%2BL%3D160%5C%5CL%3D80%5C%5CW%3D%5Cfrac%7BL%7D%7B2%7D%5C%5CW%3D40)
The garden is a rectangle with dimensions 80 ft x 40 ft.
Answer:
2 nd one
Step-by-step explanation:
Supplementary angles need to add up to 180 degrees.
Subtract Y from 180:
X = 180 - 156 = 24
X = 24 degrees
