Answer:
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
