Which of the following sets represent invertible functions? Select all that apply. 1{(2,3), ( - 2,5), (2,6),(4,6), (5,2)}
2{(2,3).(-2,5), (3, 6), (4,8), (5,2)}
3{(2,3).(-2,5), (-3,6).(-4,7), (5, 4)}
4{(2,3), ( - 2,5), (3, 6), (4, 6), (5, 2)}

a

step-by-step explanation:

a

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
