Hello! Sorry, this took a minute.

All of the x's are on the same line, and they are equal to 180 degrees.

2x+x+3x+x=180

A straight line equals 180.

Combine like terms.

7x=180

Divide both sides by 7.

25.714... round to 25.7

Now, plug that into the angle that is vertical to 2y. (3x)

3(25.7)= 77.1

So, 3x= 77.1 and 2y= 77.1

Plug that in.

2y=77.1

Divide both sides by 2.

y=38.55

Round that up to 38.6.

"D" is the answer.

I hope this helps!

Joanna plans on hanging 3 pictures of different sizes on the wall of her staircase. She thinks it will look best if all 3 rectan

Natasha2012 [34]

In similar figures, the ratio between corresponding sides are the same.

$\frac{25}{35}=\frac{35}{49}$

Simplify the two to see that they are equal.
The top and bottom of the left fraction are divisible by 5.
The top and bottom of the right fraction are divisible by 7.

$\frac{5}7=\frac{5}7$

Of course, the dimensions of that third picture would have to be this fraction.
Let's test these answers.

$\frac{5}6\neq\frac{5}7$ ⇒ A is not a solution

$\frac{30}{42}=\frac{5}7$ ⇒ B is the solution
(divide the top and bottom by 6)
