3x-22+x=180
4x-22=180
4x=202
X=202/4
X=50.5
3(50.5)-22=129.5
5-.5+129.5=180
Answer:
17
Step-by-step explanation:
T4 = 4² + 1
T4 = 4² + 1 = 17
Yip yip that's all
Answer:
four angles at point B in this second diagram.
Step-by-step explanation:
By using <span>Euler’s formula which state that:
e∧(iΘ) = cos Θ + i sin Θ
So, z₁ = 2 ( cos π/6 + i sin </span>π/6 ) = 2 e∧(i <span>π/6)
And </span><span>z₂ = 3 ( cos π/4 + i sin π/4 ) = 3 e∧(i <span>π/4)
Then </span></span>z₁ * z₂ = 2 e∧(i π/6) * <span>3 e∧(i π/4) = 6 </span><span>e∧[i (</span><span>π/6 + π/4)]
= </span><span>6 e∧(i 5<span>π/12)
= 6</span></span><span> ( cos 5π/12 + i sin 5π/12 )</span>
