Use a half-angle identity to find the exact value of sin pi/8
Answer:
the expression is x= 2.5 * z/√y
Step-by-step explanation:
since x is proportional to z and since x varies inversely as the square root of y
x= a * z/√y
then
a = x*√y /z
replacing values
a = x*√y /z = 6*√25 /12 = 30/12 = 10/4=2.5
therefore
x= 2.5 * z/√y
