Answer:
the qoustion is not correct
Answer:
Step-by-step explanation:
z=xi+yj
x=-1.2=r cosθ (say)
y=-1.6=r sinθ(say)
square and add
r²cos²θ+r² sin ² θ=(-1.2)²+(-1.6)²=1.44+2.56=4
r²=4
r=2
divide
tanθ=y/x=-1.6/(-1.2)=16/12=4/3
θ=tan ^{-1}(4/3)≈53.13°
so polar coordinates are (2,53.13°)
Answer:
x = 28
Step-by-step explanation:
The 2 angles must add up to 180°, as definition of a line.
4x + 7 + 2x + 5 = 180
6x + 12 = 180
6x = 168
x = 28
