In step one, you are supposed to add 25 to both sides, because if you just subtract, it would be -5x-50=53
P(X<=x) = 1 + 5.486 = 6.486
The z-score of the information given is,
z = (x - µ )/ σ
Where,
µ = mean
σ = standard deviation
From the information given,
x = 3.71
µ = 86
σ = √225 = 15
hence,
z = (3.71 - 86)/15 = -5.486
thus,
P(X<=x) = 1 + 5.486 = 6.486
hence , P(X<=x) = 1 + 5.486 = 6.486

<SUT is a right angle.
I believe <SUW is equal to 152 degrees.
If I did the math correctly I’d should be -5 or rewritten as -5/1.
