Answer:

C) AC

Step-by-step explanation:

<A = 72

<B = 18

The three angles of a triangle add to 180

<A + <B+ <C = 180

72+18+ <C = 180

Combine like terms

90 + <C = 180

Subtract 90 from each side

<C = 180-90

C = 90

The shortest side is opposite the smallest angle

B is the smallest angle and it is opposite side AC

Answer:

C) AC
