Find the value of x and the measure of the angle labeled 3xº.

It’s B. Because if you do 9(3)=27 that equals to the one with the identical angle 27 (on the bottom one) and the ->Angle Measure is 27<-because if you add (45) and (27) it should give you (72) for the measure of that angle. so it’s B.

The answer is biodiversity resulting from new ancestors.
