Consider, pls, this solution:
If given a equation:
-12x²+11x-3=0, then
12x²-11x+3=0
D=b²-4ac=121-12*12=-23<0
Answer:
angle Y= 60 degrees
Step-by-step explanation:
angle S + angle Y = 90 degrees because they are complementary
Y = 90 - S
angle S = 4(Y)-210
substitute for Y
S = 4(90 - S) - 210
S = 360 - 4S - 210
reduce
5S = 150
S = 30
Y = 90 - 30 = 60
