I do not know how to do this but i can tell you ^ means exponent not division. So 3^2 would be the same as
7/12.
If you make 1/3, 5/12, and 1/2 the same denominator, it will be:
4/12,5/12,and 6/12.
you can see that these fractions are increasing 1/12 for each day. so on the forth day, it will be 7/12.
T^2-t=12
t^2-t-12=0
(t-4)(t+3)=0

Answer:
angle y
58 + 38 + y = 180 (angle sum property)
96 + y = 180
y = 180 - 96
y = 84
angle x
x = 29 (58/2)
(angle subtended by an arc at centre is double the arc at any point on remaining part of centre)
the values of x = 29 and y = 84
