When any angle bisects with other angle then both the angles are equal.

Then, m of angle ABD = angle CBD

ABD = 70

ABD = CBD = 70°

ABC = 70 + 70 = 140°

Answer:

Step-by-step explanation:

because both equations add up to equal abc

we can solve for x

8x+35=11x+23

subtract 8x from boths sides

35=3x+23

subtract 23 from both

12=3x

x=4

Now we can solve for Abd

8(4)+35=67degrees =ABD

11(4) +23=67degrees=CBD

67+67=134=abc

I hope this made since sorry if it doesn't

Have a wonderful day

Answer:

$\large \boxed{\mathrm{view \ explanation}}$

Step-by-step explanation:

-45x + 40

Factor out 5 from the expression.

5(-9x) + 5(8)

Take 5 as a common factor.

5(-9x + 8)

4w + 9( -6 - 3w)

Expand brackets.

4w + 9(-6) + 9(-3w)

4w - 54 - 27w

Combine like terms.

4w - 27w - 54

-23w - 54

Question: When you do adding fractions, do you have to find a common demoniter? *sorry for misspelling*

docker41 [41]

Answer: yes when your adding or subtracting fractions you must find the common denominator between the two before you continue.

Step-by-step explanation:

Example: 2/4+3/2

Find the common denominator. ( in this case the common denominator is 4)

We keep the first fraction as it is cause it has the denominator 4 and we multiply the second fraction by 2 up and down to get a denominator of 4. The equation becomes 2/4+6/4

Now you add the numerators and you got your answer ( don’t forget to simplify)

The answer after adding in this case is 8/4 and when simplified it is 2
