Answer:

y = 37

Step-by-step explanation:

Since we know all the terms will equal 180°, we can set up the following equation to solve for y:

y + 29 + 40 + 2y = 180

3y + 69 = 180

3y = 111

y = 37

Answer:

y=10

4 SX +20 Y= 822

Elimination

X - 10 -4

UX - 822-20Y

6.5

10 -4 = 822-201

45

- 4.5 = 822 - 204

Will mark BRAINLIST Find the perimeter of the following shape, rounded to the nearest tenth: coordinate plane with quadrilateral
kolbaska11 [484]

Answer:

11.3 units

Step-by-step explanation:

Let's find the length of one of the boxes.

a^2+b^2=c^2\\1^2+1^2=c^2\\1+1=c^2\\2 = c^2\\\\\sqrt{2} = c\\ c = 1.414...

Let's simplify c down to 1.41.

Now, there are 8 of these little boxes for the perimeter, let's multiply.

1.41\cdot8=11.28

That can be simplified to the nearest tenth - 11.3

Hope this helped!
