Answer: C) ∠ABC & ∠DBC

Step-by-step explanation:

When a ray bisect an angle , then it divided the original angle into two congruent angles.

We are given that Ray BC bisects angle ABD.

Then, Ray BC divides ∠ABD into two congruent angles.

From the picture, The angle formed by it : ∠ABC & ∠DBC

So ∠ABC & ∠DBC must be congruent.

Hence, the pair of angles must be congruent : ∠ABC & ∠DBC

Congruent is the same size and same shape. When a ray bisects an angle, the two newly created angles will be congruent, since the ray went right in the middle of the first angle (so in this case, ABC and DBC will be congruent)

Help! given 2(x-9)=-10 prove x=4 with statements and reasons

Sedbober [7]

Step-by-step explanation:

Proof:

2 ( x - 9) = - 10 when x = 4

2 ( 4 - 9) = -10

8 - 18 = -10

-10 = -10 ..........hence proven

Reasons 

- When you replace X with 4, you can clearly see that the equation is equal to -10.

sorry I couldn't answer accurately, but I hope this helps

Answer:

D) 50/3

Step-by-step explanation:

6/10 = 10/(6+x-6)

6/10 = 10/x

6x = 100

Y-5=-1/2(x+7) (find the slope)

sashaice [31]

It's the slope-point formula:

$y-y_1=m(x-x_1)$

We have:

$y-5=-\dfrac{1}{2}(x+7)$

Therefore, the slope $m=-\dfrac{1}{2}$
