CHECK THE ATTACHMENT FOR THE FIGURE OF THE QUESTIONS
Answer:
Option A. is correct x = 4
Step-by-step explanation:
From the given figure
The adjacent of the given right angle triangle is
8 units which is the base,
Then x units is the opposite of the right angle triangle which is the height.
The hypotenuse side also has x units
Then value of x is required,
But going by right angle triangle trigonometry
cos(x) = adjacent / hypotenuse
Where adjacent= 8 unit
cos( 60) = 8/x
1/2 = 8/x
x = 8/2
= 4unit
Hence, Option A is correct, with 4 units
