82 boats. because 1/7 is 3 boats and then x 7 and then x 3 + 21
It could be a building with a triangular top. If the building had a triangular top, then it must have 3 rectangles as its sides. So your answer would be, a building with a triangular top.
Answer:
i think it is -7-24i
Step-by-step explanation:
you have to write it in the form a+bi, so a=-7 and b=-24
Answer:
its B
Step-by-step explanation:
It is easy after using formula of t<span>he complex numbers
</span>z1= 5(cos25Deg + i sin25Deg)
z2= 2(cos80Deg + isin80Deg)
so z1/z2 =5/2cis(25Deg-80Deg)=5/2cis(-55Deg)
but we know that sin(-55Deg)= - sin(55Deg), and cos(-55Deg)=cos(55Deg),
finally the answer is Z=5/2(cos55Deg-i sin55Deg) (Z=z1/z2)
