Answer:
z =15cm and
y=9.0cm
Step-by-step explanation:
Use sine rule
12/ sin53 = z / sin 90
Z = 12 x sin 90 / sin 53
Z = 15cm
To find y the angle opposite to y will be 180-(90+53)=37º
So
15/sin 90= y/sin37
y= 15 x sin37 /sin 90
y = 9.0cm
20.25-9(1/2)+11
=20.25-4.5+11
=26.75
Answer:
108 degrees
Step-by-step explanation:
Answer:
4-6i has coordinate (4,-6), and -4+2i has coordinate (-4,2)
Step-by-step explanation:
The real part of the number represents the x coordinate, the imaginary part is the y coordinate, so 4-6i has coordinate (4,-6), and -4+2i has coordinate (-4,2)
we are given

we can see that
numerator is

and denominator is

We always put coefficient of numerator inside box
we can see that coefficient of numerators are 3 , -4 and 9
and in the left side , we put value of x after putting denominator =0


so, left side will be 2
so, option-D..................Answer
