Since BE bisects angle ABC, you know that angles ABE and EBC are congruent and have the same measure. This means

2x + 20 = 4x - 6

Solve for x:

(2x + 20) - 2x + 6 = (4x - 6) - 2x + 6

26 = 2x

26/2 = 2x/2

13 = x

Then angle ABE has measure 2*13 + 20 = 46º.

A complete table with values for x or y that make this equation true:3x+y=15
Andreyy89

Answer:


Step-by-step explanation:

The given equation is: 3x+y=15,

Now, putting x=2 in above equation,

3(2)+y=15

y=15-6=9

Now, put y=3 in the given equation,

3x+3=15

3x=12

x=4

Putting x=6,

3(6)+y=15

y=15-18y=-3

Putting x=0,

0+y=15

y=15

Putting x=3,

3(3)+y=15

y=15-9

y=6

Putting y=0,

3x+0=15

x=5

Putting y=8,

3x+8=15

3x=7

x=\frac{7}{3}

What is the value of x
gayaneshka [121]

Answer:

Assuming the other side is 30, x=12

Step-by-step explanation:

X+(X+6)=30

2x+6=30   (open the brackets by distributing the plus sign inside)

2x=24       (subtract 6 from both sides)

x=12          divide both sides by 12

This makes sense because of x is 6, and x+6 is 18, 6+18=30.

a. Write and simplify the integral that gives the arc length of the following curve on the given integral. b If necessary, use t
WINSTONCH [101]

Answer:

\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

Step-by-step explanation:

Arc length is calculated by dividing the arcs in to small segments ds

By pythagoren theorem

ds^2=dx^2+dy^2

then integrate ds to get arc length.

We are given a function as

y = sin 2x in the interval  [0, pi/2]

To find arc length in the interval

Arc length s =\int\limits^{\pi/2} _0 {1+y'^2} \, dx \\=\int\limits^{\pi/2} _0 (1+4cos^{2} (2x) )dx

Hence arc length would be

B) \int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

PLEASE HELP TOP ANSWER GETS BRAINLIEST!! ***Solve for m: 3.2(4m + 10) – (-7.2m) = 37 ***!!!!!!!
alisha [4.7K]

Answer:

1/4 or 0.25

Step-by-step explanation:

  • 3.2(4m + 10) – (-7.2m) = 37
  • 12.8m+32+7.2m=37
  • 20m= 37-32
  • 20m=5
  • m=5/20= 1/4 or 0.25
