Inessa [10]

Answer:

l = 24ft

Step-by-step explanation:

A = lw

360 = (x + 9)(x)

360 = x^2 + 9x

0 = x^2 + 9x - 360

0 = (x + 24)(x - 15)

x ≠ -24 (length cannot be negative)

x = 15

l = 15 + 9

l = 24ft

What is the value of y?

mojhsa [17]

<h2>QUESTION:- What is the value of y?</h2>

<h2>ANSWER:- </h2>

SUM OF ALL INTERIOR ANGLE = 180

$y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 72 \\ 2y = 108 \\ y = \frac{108}{2} \\ y = \frac{ \cancel{108}^{ \: \: \: \tiny{54}} }{ \cancel{2}} \\ y = 54 \degree$

Help me out please simple

const2013 [10]

<u>A straight line is 180 degrees in measure</u>

<u>The straight line is made up of three angles</u>

--> angle 1

--> angle 2

--> angle with a little square on it

(<em>angle with a little square means it is 90 degrees in measure)</em>

<u>Let's set up an equation</u>

$angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3$

Thus angle 1 is <u>3 degrees</u> or the <u>second choice</u>

<u></u>

Hope that helps!
