how do i find the value of "x" in a adjacent angle ?

Question

how to find the value of x in adjecent angel

Answer 1

We can use the three basic trigonometric functions to find the missing sides.

 

Sine, cosine, and tangent.

 

We use the following trick to determine when we use these trig functions:

 

SOH: sinθ = side opposite of angle over hypotenuse

CAH: cosθ = side adjacent to angle over hypotenuse

TOA: tanθ = side opposite of angle over side adjacent to angle

 

θ = angle

 

In this case, we use the cosine function.
