The measure of the angle x or the value of x is 20 degrees after applying the sin ratio in a right-angle triangle DCB.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a right-angle triangle shown in the picture.
From the right angle triangle we can find the value of x or measure of the angle x by applying the trigonometric ratios:
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying sin ratio in a right-angle triangle DCB:
sinx = 50/146
sinx = 0.342
x = 20.02 ≈ 20 degrees
Thus, the measure of the angle x or the value of x is 20 degrees after applying the sin ratio in a right-angle triangle DCB.
