Step-by-step explanation:
From the question we are told that:
Angel of side 
Angel of side 
Length Side 
Generally the equation for Angle of side ST
is mathematically given by
Since Angle in Triangle =180 therefore


Therefore Applying sine rule to get Length of ST x



Answer:

Answer:
discriminant=D=0
Step-by-step explanation:
given, 9x^2-18x+9=0...............(1)
equ (1) divided by 9
x^2-2x+1=0
discriminant=D=b^2-4ac
where, b=-2, a=1, c=1
D=(-2)^2-
D=4-4=0
D=0
hence discriminant=D=0 answer
