Angle x is an acute angle in a triangle. if cos x=4/5, then the sin x=

Step-by-step explanation:

Angle x is an acute angle in a triangle.

The measure of cosine angle is given to be :

Now, we need to find the measure of the sine angle for the same triangle.

⇒ Base = 4 units and Hypotenuse = 5 units

So, Length of perpendicular = 3 units ( By using Pythagoras theorem)
