Answer:

1 cm

Step-by-step explanation:

To solve this problem we can use the Pythagorean theorem. In fact the diagonal of a rectangle is an hypotenuse of a right triangle, while the length is a leg. The width is the other leg

width = √2^2 - (√3)^2 = √4 - 3 = √1 = 1 cm

Which line represents the direct variation equation y = 1/2x?
Verdich [7]

Answer:

C.

Step-by-step explanation:

y = 1/ x must pass through the origin because when x = 0, y = 0.

So its either B or C.

A positive slope rises to the right ( 1/2  is positive), so its C.

You can also see that the slope of C is 1/2 because it passes through the points (0.0) and (2, 1).

A)<br>be<br>85°<br>120°<br>(2x - 10°<br>X​
Lunna [17]

Let's see what to do buddy...

_________________________________

Step (1)

We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :

(n - 2) \times 180

Our figure has 5 sides ;

So , sume the interior angles of it equals :

(5 - 2) \times 180 = 3 \times 180 = 540 \\

_________________________________

Step (2)

First look at the photo which I post.

According it we have :

(180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\

2x - x + 475 - 10 = 540

x + 465 = 540

Subtract the sides of the equation minus 465 :

x = 540 - 465

x = 75

_________________________________

And we're done.

Thanks for watching buddy good luck.
