If it has 3 sides then it's a triangle.
Using the formula
where
and a=5 b=5 c=8
∴
Add 8 to both sides
3x=33
Divide both sides by 3
x=11
Answer:
this probably isn't right, but with an educated guess it's probably the third answer.
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Since both chords are congruent and the distance of the x and 7 are equidistant from the center, then the value of x will also be 7.
Left side chord will have a value of y + 10
The right side chord will have a value of y + 10
Now since the right angles on both sides are equal, then x = 7.
