Answer:
r=
Step-by-step explanation:
Circumference formula: 2πr
2πr=15
Divide 2π on both sides.
So since it won't be a integer you can leave it live that so your final answer will be:
r=
The answers are:
a = c
c = d
b + d =180 degrees
Here's how:
When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.
option c = d is considered.
And, because of vertical angles,
a = d is also an answer.
