Answer
Find out the value of x.
To prove
By using the trignometric identity

As given in the diagram.

Perpendicular = x
Hypotenuse = 6
Put in the above identity


Put in the above

x = 4.6 cm (Approx)
Therefore Option (c) is correct .
Answer:
x=4
Step-by-step explanation:
First you want to add 8.8 to 7.2 and get 16 because you want to get x alone
Next divide divide 4x on both sides so 4x/4x cross out and left with just x. 16/4 =4
x=4
