The theorem is used to find the side and angles of a triangle. The value of y from the given diagram is 0.64
SOH CAH TOA identity
The given diagram are right angled triangle
From the lower triangle
sin45 = a/2√2
1/√2 = a/2√2
1 = a/2
a = 2
Determine the value of y
tan 60 = opp/adj
tan 60 =y/2
y = 2 tan60
y = 0.64
Hence the value of y from the given diagram is 0.64
