[40 points] in δabc, ∠a = 72 and ∠b = 18. what is the shortest side of the triangle? a) ab b) bc c) ac d) cannot be determined

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

i hope that is right.
