WAR is given as 57 degrees.

If you draw a line from W to R, the angle WRA would also be 57 degrees.

57 + 57 = 114

The measure of AR = 180 -114 = 66 degrees.

b. Use de Moivre's Theorem to compute the following: b. ^3√(8cos(4π / 5) + 8isin(4π / 5)). This is the only one i need help with
pochemuha
De Moivre's Theorem states that if a complex number is written in the polar coordinate form [ r (cosθ + isinθ)] and you raise it to the power n, then this can be evaluated by raising the modulus (r) to the power and multiply the argument (θ) by the power.  This therefore would give r ⁿ  [cos (nθ) + i sin (nθ)].

let A =  ∛ <span>(8 cos (4π / 5) + 8 i sin (4π / 5))

</span>⇒  A = ∛ <span>(8 [cos (4π / 5) + i sin (4π / 5)])
</span>
Now by applying De Moivre's Theorem,

⇒ A = 8^{ \frac{1}{3} } [cos (\frac{4 \pi }{5} × \frac{1}{3}) + i sin (\frac{4 \pi }{5} × \frac{1}{3})

⇒ A = 2 [ cos (\frac{4 \pi }{15}) + i  sin (\frac{4 \pi }{15})

⇒ A = 2 [0.0117 +  i 0.01297 ] rads

Answer:

4x² - 10x + 1

Step-by-step explanation:

(3x-1) + (x+2) + (3x² - 11x) + (x² - 3x)

3x - 1 + x + 2 + 3x² - 11x + x² - 3x

1 - 10x + 4x²

= 4x² - 10x + 1
