Answer:

Step-by-step explanation:
Using De Moivre's theorem
Given
[ 4(cos15° + isin15° ) ]³, then
= 4³ [ cos(3 × 15°) + isin(3 × 15°) ]
= 64 (cos45° + isin45° )
= 64 (
+ i )
= 64 ( (1 + i) )
= 32
(1 + i)
= 32 + 32 i

Step-by-step explanation:
Answer: If the question is formed as (- 3/5) x = 15
then A is correct
X=-25
Step-by-step explanation:
Answer should be 1.85 x 10^18
Answer:
Step-by-step explanation:
Sin(35) = opposite / hypotenuse
Sin(35) = 4 / hypotenuse Multiply both sides by the hypotenuse
hypotenuse * sin(35) = 4 Divide by Sin(35)
hypotenuse = 4/Sin(35)
Sin(35) = 0.5736
hypotenuse = 4/0.5736
hypotenuse = 6.9737
Rounded answer 6.97
