Intersecting chords form a pair of supplementary, vertical angles. True or false.
2 answers:
Answer: True
Step-by-step explanation:
When two lines intersect they form both supplementary and vertical angles.
For example if AB intersects CD at point O (as given in figure), then ∠AOD and ∠DOB are supplementary [lies on line AB] and ∠AOB = ∠COB {Vertical angles are congruent}
Since Chords are line segments that join two distinct points on the circle, it means Intersecting chords also form a pair of supplementary, vertical angles.
Hence, the given statement is true.

I'll do 22 for you. 22, 24, 26, 28, and 30, are very similar to each other.
PROPORTIONS:
Draw it out.
5/7 = either c/6, or b/5.
I'll do c/6
5/7 = c/6
solve for c
7c=30
c=30/7
now do the same thing to the remaining side, b.
there!
