X+16 5/6 mixed number is the 5/6
<u>Answer:</u>

<u>given:</u>
- adjacent side: 10
- hypotenuse side: 20
<u>using cosine rule:</u>




If angle 1 and angle 2 are <u>complementary, </u>then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.
So we subtract and get our answer:
38
That's NOT the final answer.
The next step is:
Angle 1 and angle 3 are vertical angles.
Vertical angles are congruent.
So if angle 1 is 38, then angle 3 is also 38.
Now, supplementary angles add up to 180 degrees.
So that's the answer:
180-38=142
142 is the supplement of angle 3.
Hope it helps! :)

If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
