Answer:

Step-by-step explanation:

if you are given diameter ,then radius=diameter/2

if you are given the co-ordinates of extremities of diameter then find diameter by distance formula and then radius as given above.

if area is given the area=πr²

r=√(area/π)

if circumference C is given then C=2πr

r=C/2π

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

m∠1+∠2=180

2x+40+2y+40=180

2x+2y=180-80

2x+2y=100

x+y=50

x=50-y

m∠1=m∠3

2x+40=x+2y

2x-x=2y-40

x=2y-40

2y-40=50-y

2y+y=50+40

3y=90

y=30

x=50-y=50-30=20

m∠1=2x+40=2×20+40=80°

m∠2=2y+40=2×30+40=60+40=100°

m∠3=x+2y=20+2×30=80°
