Answer:

Step-by-step explanation:

I still suspect that Angle A is 30° and Angle B is 60°. Otherwise the labels do not fit the illustration.

If Angle A is 60°, as you insist, then the solution (the length of x) is as follows:

opp side x

tan 60° = √3 = ---------------- = -----

adj side 7

Then:

√3 x

----------- = -----

1 7

Thru cross-multiplication we see that x = 7√3

Multiply both sides by 7, which produces:

7√3 = x

Which pair of numbers have a greatest common factor of 7?

ella [17]

<span>The GCF is the number that is a factor of both (or all) of the numbers of a given set and which is the biggest factor of this kind (often the smaller number of the two)

7 and 14 have a greatest common factor of 7.

28 and 7 also have a GCF of 7, so the first two responses fit.

21 and 3 have a GCF of 3, so that isn't correct.

7 and 1 have a GCF of 1, so that's incorrect as well.</span>
