Answer:
x = 24.7
Step-by-step explanation:
Here, we want to find the value of x
To do this, we are to use the appropriate trigonometric ratio
From what we have;
9 faces the angle given as it is the opposite, x is below and it is the adjacent
The trigonometric identity that links opposite to adjacent is the tan which is the ratio of former to latter
Thus, we have that;
tan 20 = 9/x
x = 9/tan 20
x = 24.7
