Answer:
B
Step-by-step explanation:
Here, we want to the find the value of the x.
By bisecting the angle, the ray in question divides it into two other angles which are equal.
We proceed as follows;
x + 7 = 2x -11
Collect like
terms
2x -x = 7 + 11
x = 18
Answer:
Had two congruent sides
Has congruent base angles
There are several ways two triangles can be congruent.
<em> congruent by SAS</em>
<em> congruent by corresponding theorem</em>
In 
and 
(see attachment), we have the following observations
--- Because O is the midpoint of line segment AD
--- Because O is the midpoint of line segment BC
---- Because vertical angles are congruent
---- Because vertical angles are congruent
Using the SAS (<em>side-angle-side</em>) postulate, we have:
Using corresponding theorem,
---- i.e. both triangles are congruent
The above congruence equation is true because:
- <em>2 sides of both triangles are congruent</em>
- <em>1 angle each of both triangles is equal</em>
- <em>Corresponding angles are equal</em>

Put it like that and there’s your constant
Hypotenuse^2=12^2+5^2=144+25=169
⇒ hypotenuse =V169=13 cm
