A meter is 100 cm, so 4 m = 400 cm.
1 cm : 4 m = 1 cm : 400 cm = 1 : 400
Answer:
LHS=cos^4(A/2)-sin^4(A/2)
={cos^2(A/2)}^2 -{sin^2(A/2)}^2
={cos^2(A/2) - sin^2(A/2)}{cos^2(A/2) +sin^2(A/2)}
=cosA×1
=cosA
Answer:
600
Step-by-step explanation:
Answer:
b = (a - 6)/2h
Step-by-step explanation:
a = 2bh + 6 (subtract 6 from both sides)
a - 6 = 2bh (divide both sides by 2)
(a - 6)/2 = bh (divide both sides by h)
(a - 6)/2h = b
