Each exterior angle = (360° / number of sides)
Each exterior angle = 3.6°
Answer:
80
Step-by-step explanation:
volume of rect. prism = 10 units^3
volume of each cube =1/2*1/2*1/2
= 1/8 units^3
required cubes = 10/1/8 = 80
Answer:
19g^2
Step-by-step explanation:
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS
