Answer: A √28 41°
Explanation:
You can use pythagorean to solve for x
c² = a² + b² >c is the hypotenuse, always across from the 90 angle
> a and b are the legs doesn't matter which you
choose to be a or b
8² = x² + 6²
64 = x² +36 >subtract 36 from both sides
x² = 28
x = √28
To find the angle, use SOH CAH TOA. You can use any of them because you have all of the sides but I'm going to choose CAH because i don't want to deal with root.
cos x = adjacent/hypotenuse
cos <E = 6/8
<E = cos⁻¹ (6/8)
<E = 41
