Answer:

hello

Step-by-step explanation:

adjacent angles are equal to 180 degrees,

$(2x + 9) + (5x + 3) = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{168}{8} \\ x = 21 \\ \\$

but, for some reason, does not match the answers…

Can the answers be wrong?

or I miscalculated…

i hope it helps have a nice day

Answer:

Step-by-step explanation:

(2x + 9 )+ (5x + 3) = 180

x = 24

(I just guessed and checked. It was multiple choice so why not?)

X = 33

The angles are corresponding, so they must be congruent. You set 4x-8 equal to 124 because they are congruent. You then add 8 on both sides and divide by 4 on both sides. You should get 33 for x.

Me voy a comprar una barra de cortinas. Como vivo en un doceavo piso, me interesa saber cuál es la longitud máxima que puedo met

Answer:

The maximum length of the bar I could fit in the elevator is 2.87 meters.

Step-by-step explanation:

<u><em>The question in English is</em></u>

I'm going to buy a curtain rod. Since I live on a twelfth floor, I'm interested in knowing the maximum length I can put in the elevator.

So I take out my pocket tape measure, which only measures up to a meter and I measure the floor which turns out to be a square of 1m x 1m, but for the height it doesn't give.

However, there's a sticker on the lift box that says it has a capacity of 2,500 litres.

With all this information, what is the maximum length of bar that would fit me in the elevator?

step 1

Find the height of the elevator

we know that

The elevator has a capacity of 2,500 litres.

$1\ m^3=1,000\ L$
