On a piece of paper, use a protractor to construct △abc with m∠a = 30° , m∠b = 60° , and m∠c = 90° .

which statements about the triangles are true?

a. ac > ab

b. ac > bc

c. ac < bc

d. ac < ab

Here, we know largest side is always opposite to the largest angle.
As largest angle is C with 90 degree, it's opposite side which is AB must be longest here!! & AC would be second largest & BC would be smallest.

In short, Your Answer would be Option B & D

Hope this helps!
