Answer:
Use the cosine function where x° = 63.43°
Step-by-step explanation:
In relation to angle x°, side 3 is adjacent, and side 3√5 is the hypotenuse. Therefore, the trig function that uses the adjacent and hypotenuse is the cosine function. You would then set your equation up and solve for x°:
cos(x°) = adjacent/hypotenuse
cos(x°) = 3/(3√5)
x° = cos⁻¹(3/(3√5))
x° = 63.43°
