Question

How do i find the value of x and the sine, cosine, and tangent of this angle?​

Answer 1

To find x, you first have to find the values of the other two sides.

√6=2.5

√15=3.9

Then you would use the Pythagorean theorem.

2.5²+3.9²=21.46

x=√21.46 or 4.6

Now that we have found all three sides it will be easier to find the sine, cosine, and tangent of the triangle using the ∅ sign in the top of the triangle.

For sine it would be the opposite/hypotenuse.

Sin2.5/4.6= 0.5

For cosine it would be adjacent/hypotenuse.

Cos3.9/4.6=0.7

For Tangent it would be opposite/adjacent.

Tan2.5/3.9=0.8
