X can be either 1.33, 0.382, 0.053, or 0.094, we can solve each equation separately by dividing both sides of each equation by the coefficient of x.

To find x, we can look at the given equations:

15x = 20

17x = 6.5

19x = 1

21x = 1.97

We can solve each equation separately.

For the first equation, we divide both sides by 15: x = 20/15 = 1.33

For the second equation, we divide both sides by 17: x = 6.5/17 = 0.382

For the third equation, we divide both sides by 19: x = 1/19 = 0.053

For the fourth equation, we divide both sides by 21: x = 1.97/21 = 0.094

So x can be either 1.33, 0.382, 0.053, or 0.094.

Explanation:

so this very figure requires the trigonometric functions to solve for x

we begin by getting to know each trigonometric functions, which are tangents,consine and sine

tangent=opposite/adjacent

cosine=adjacent/hypotenuse

sine=opposite/hypotenuse

we solve for x by using the cosine trigonometric function

cos∅=17/x

cos(50)=17/x

here we do change of subject where x becomes the subject

x=17/cos(50)

x=17/0.643

x=26.45

which when run to the nearest whole number becomes 27

therefore x=27
