This is a right triangle. We know that

                                                 \tan x = \frac{\text{opposite side}}{\text{adjacent side}}

Therefore,

                                              \tan x = \frac{18}{21} = \frac{6}{7} = 0.857

Now we have:

                                                 x=\tan^{-1}0.86

                                                       x=40.6

Answer:

Commutative property of multiplication

Step-by-step explanation:

Commutative property of multiplication basically means that the order in which you multiply numbers does not matter.

For exampe:

3 x 4 = 4 x 3

    12 = 12

In your case:

5 x 7 x 4 = 5 x 4 x 7

        140 = 140

If we break that down:

5 x 7 x 4 = 5 x 4 x 7

   35 x 4 = 20 x 7

        140 = 140
