Need asap 70 points given: △ace, bd¯¯¯¯¯∥ae¯¯¯¯¯ prove: ba/cb=de/cd drag an expression or phrase to each box to complete the proof.

Ayo, for anyone who needs it -

Step-by-step explanation:

Statement                                                                Reason

ΔACE, BD║AE                                                          Given

∠4≅∠1 and ∠3≅∠2                                      Corresponding angle postulate

ΔACE is similar to ΔBCD                             Angle-Angle similarity postulate

         Definition of similar triangles

CA=CB+BA and CE=CD+DE                        Segment addition postulate

Substitution property of equality.

Addition of fractions.

   Simplification of fractions

        Subtraction property of equality.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
