Equate real part and imaginary part:
LHS:
real part -- 12
imaginary part -- 5y
RHS:
real part = 4x
imaginary part = 25
Equating::
12 = 4x
x = 12/4
x = 3
Again:
5y = 25
y = 25/5
y = 5
So,
x = 3
y = 5
Answer:
B. 70°
Step-by-step explanation:
If this is an equilateral triangle, then each angle is 180/3 = 60
<A = 60 = x+3x+2x
60 = 6x
60/6 = 6x/6
10 =x
Angle B will also equal 60 degrees
BDA + x + B = 180
BDA + 10 + 60 = 180
BDA + 70 = 180
BDA = 180-70
BDA = 110
BDA and y are complementary angles since they form a straight line
BDA + y = 180
110 +y =1 80
y = 180-110
y = 70
Answer:
y=-1/2
Step-by-step explanation:
9x+5y=8
9x-3y=12
so 8y= -4
y=-1/2
if my answer helps please mark as brainliest

Answer:
I would say: D, C, A.
Step-by-step explanation:
A cylinder consists of 2 bases. This means that they are both congruent (having the same measure). They are also both in the shape of a disc. These two bases are both parallel being opposite of one another. I would appreciate if you thank me or mark me as brainliest :) (I have never had brainliest before)
