What is the approximate value of y - x

17.2°

Step-by-step explanation:

using the tangent ration in the right triangle

tan y° = = , hence

y = () ≈ 53.6°

tan x° = , hence

x = () ≈ 36.4°

y - x = 53.6° - 36.4° = 17.2°

D) y -x = Approximate 17.1 degree.

Step-by-step explanation:

Given : Triangle .

To find :  Approximate value of y - x.

Solution : We have given a right angle triangle with

Opposite side = 19.1 in.

Adjacent side = 14 .1 in.

Tan( y ) = .

Plug the values

Tan( y ) = .

tan(y) = 1.354.

Taking tan inverse both sides.

y = .

y = 53.55 degree.

Now, by the sum of angle of triangles is 180 degree.

Angle c + angle y + angle  x = 180.

Plug the variable

90 + 53.55 + x = 180.

83.55 + x = 180

On subtracting both sides by 83.55

x = 36.45 degree

Then ,

y - x = 53 .55 - 36 . 45

y - x = 17.2

Approximate 17.1 degree

Therefore, D) y -x = Approximate 17.1 degree.

hope this ! (:   mark me as brainliest if you can

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
