Idon't will give brainliest answer!
when solving for x in the figure above, ryan divided 9 by square root of 3. explain why ryan needed to do one more step before he was finished solving for x.

Rationalising the denominator is what I would do (figure may imply differently) if x= 9/root 3, then times both the denominator and numerator by Root3, leaving 9*root3/Root3*Root3

This cancels down into 9*Root3/3 because a root*root of the same number= that number

9 times Root 3 all over 3

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

Your answer should be “b” i truly hope i could ! good luck (:
