To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33
Answer:
omg that one is hard but it is 18j-6m
The answer is 25, leave a like (:

is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)

(or 30 degrees)
sin
