A diagonal of a rectangle cuts the rectangle into 2 right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.

Vanessa wants to determine the perimeter around her garden. She makes an small model of her garden and combines all the sides: 3

son4ous [18]

Answer:

4

Step-by-step explanation:

since it's all addition, we can remove the parentheses

$3x + x + 10 + 5x + 2x + 2 = 56$

Now we combine like terms

$3x+x+5x+2x+10+2=56$

$11x+12=56$

We subtract both sides by 12 to get,

$11x=44$

now we divide both sides by 11

$x=\frac{44}{11}$

$x=4$

X and y<br> are supplementary angles. y<br> measures 156<br> What is the measure of a?

Troyanec [42]

Supplementary angles need to add up to 180 degrees.

Subtract Y from 180:

X = 180 - 156 = 24

X = 24 degrees
