Answer:

The answer is the option D

m∠BED= $135\ degrees$

Step-by-step explanation:

we know that

If lines L and M are parallel

then

m∠CBE=m∠BED ------> by alternate interior angles

we have

m∠CBE= $135\°$

therefore

m∠BED= $135\°$

D) 135° due to the fact you only need to turn it.

GIVING BRAINLIEST HELP ASAP!! 3x + 5y = 12 in slope intercept form please show work

Answer:

y= -3/5x + 12/5

Step-by-step explanation:

<u>Remember, the formula is y= mx + b</u>

#1 So we're gonna put it into that order by subtracting 3x from both sides:

3x + 5y= 12

-3x -3x

We are left with this:

5y= -3x + 12

#2 Now we will divide 5 to both sides to isolate the variable

5y/5= -3x/5 + 12/5

#3 Now that the variable is isolated we are left with the answer:

y= -3/5x +12/5

Hope this helps :)

Please help me <br> I have to solve the triangle with the law of sines

Nikitich [7]

Check the picture below.

and since a triangle has a sum of 180° for all interior angles.

A = 180 - 39.34 - 25

A = 115.66

$\bf \cfrac{sin(25^o)}{44}=\cfrac{sin(A)}{a}\implies \cfrac{sin(25^o)}{44}=\cfrac{sin(115.66^o)}{a} \\\\\\ a\cdot sin(25^o)=44\cdot sin(115.66^o)\implies a=\cfrac{44\cdot sin(115.66^o)}{sin(25^o)} \\\\\\ a\approx 93.8452\implies \stackrel{\textit{rounded up}}{a = 93.85}$
