Question

If tanº 45 - cos^2 30 = x sin 45 cos 45, then x =​

Answer 1

Step-by-step explanation:

If tanº 45 - cos^2 30 = x sin 45 cos 45, then x =

tanº 45 - cos^2 30 = x sin 45 cos 45

1 - 1/2*2= x

4-1/4 = 3/4 = x

Answer 2

Answer:

x=1/2

Step-by-step explanation:

tan 45°=1,cos 30°=√3/2,sin 45°=cos 45°=1/√2

1-(√3/2)^2=x 1/√2 ×1/√2

1-3/4=x×1/2

1/4=x×1/2

x=1/2
