Answer:
AD is the diameter
Step-by-step explanation:
Angles in a triangle have a sum of 180°, so inscribed angle B is 80° and inscribed angle E is 90°.
An inscribed angle subtends an arc that is twice its measure, so arcs ABD and AED are both 180°. That makes chord AD a diameter.
Points A and D need your cross markings. AD is a diameter of the circle.
You can use the formula x2-x1 over y2-y1
A- 20%
B- 25%
C- 10%
