How do you find the perimeter of a rectangle with diagonal

Mathematics

All the sides of a proper rectangle are 90 degrees. 
<span>So you use sine and cosine to figure out the two different lengths of sides ( because rectangle sides are parallel). To find area you times the two sides together. To find perimeter you times the two sides by two and add them together.</span>

(5p-9)(5p-9) find each square
Iteru [2.4K]

Answer:

The square would be 25p^2 - 90p + 81

Step-by-step explanation:

To get this, use the FOIL method. In this, we multiply the first, outer, inner and last pairings.

First - Multiply the first number in each parenthesis.

5p * 5p = 25p^2

Outer - Multiply the outside numbers in each parenthesis.

5p * -9 = -45p

Inner - Multiply the inner numbers in each parenthesis.

-9 * 5p = -45p

Last = Multiply the last numbers in each parenthesis

-9 * -9 = 81

Now take all of those numbers and add together. Then simplify.

25p^2 - 45p - 45p + 81

25p^2 - 90p + 81

Everything is in the screen shoot
sattari [20]

Answer:

z = 106°

As a straight line has total 180°

Find the top inside angle:

t + 142° = 180°

t = 180° - 142°

t = 38°

Two opposite angles sum up to exterior angle.

<u>Now find z:</u>

68° + 38°

106°
