answer in 5 mins
if tan square 45 - cos square 30= x sin 45 then x equals

Answer 1

Answer:

Step-by-step explanation:

1-[√3/2] X*1/√2*1/√2

=4-3/2=X/2

=when 2 get cancelled

=x=1

Answer 2

Answer:

x = 1 / 2√2

Step-by-step explanation:

Tan^2 45° = 1^2 = 1

Cos^2 30° = ( √3 / 2 )^2 = 3 / 4

Tan^2 45° - cos^2 30° = 1 - 3 / 4 = 1 / 4

=) 1 / 4 = x sin 45°

=) 1 / 4 = x * 1 / √2

=) x = √2 / 4

=) x = 1 / 2√2
