Fill in the blank with the correct response.

x=4

Step-by-step explanation:

Notice that the angle between side x and side 2 in the small right triangle on the left is the same angle between the sides x and (2+6 = 8) in the larger right angle triangle.

if we name the angle in question , then we have for the small triangle on the left, the following trigonometric relationship:

because in that small triangle, the side adjacent (adj) to angle  is "2" and the hypotenuse (hyp) is "x" .

We can set some similar relationship for the larger triangle, which has a hypotenuse (hyp)  of length (2+6 = 8), and that has for side adjacent (adj) to the angle side "x":

Now, we can make both expressions equal since they involve the same angle, and solve for "x" in the resultant formula:

therefore x is either "4" or "-4" to give 16 when squared.

We opt for the positive answer since we want a length.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
