The value of x is 8 units after applying the cos ratio option (D) 8 is correct.
What is a right-angle triangle?
It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have a right-angle triangle shown in the picture.
As we know, Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle that is equal to the sum of the squares of the other two sides.
The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying the cos ratio to find the value of x:
cos37 = x/10
x = 10cos(37)
x = 7.98 ≈ 8 units
Thus, the value of x is 8 units after applying the cos ratio option (D) 8 is correct.
