Write one-hundred-two-and-eighty-one-hund redths in standard form. A 120.081 B 102.081 C 102.81 D 102.801

c

Step-by-step explanation:

Your CORRECT answer will be B

Step-by-step explanation:

It is definantely not A, because it 102, not 120, so it b, c, or d.

102.081 sounds exact, but what about C? You cannot leave out the 0, so that's out too! 102.801? Say it out loud, doesn't make sense! So you have only one answer left, C.

Mark me brainliest!

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
