Answer:
Option (a) is correct.
To find the value of x, use
Step-by-step explanation:
Given : a right angled triangle with some given measurements.
We have to choose the correct calculation for the value of x.
Consider the given Right angle triangle.
Using trigonometric ratio,
We know, Sine gives the relationship between perpendicualr and hypotenuse of a triangle.
Thus,
For
We have Perpendicular = x and hypotenuse = 8
Thus, Substitute, we get ,
Multiply both side by 8, we have,
Thus, To find the value of x, we use
