Answer:
XY = AB is the correct option
Step-by-step explanation:
Given in the picture are two triangles ABC and XYZ
These two triangles if congruent will have corresponding sides and angles congruent.
We have corresponding sides as AB, XY or BC, YZ or CA, ZX
Hence out of the four options given correct option is
XY = AB
(since already two angles are congruent)
By ASA if one side is congruent the triangles would be congruent
Hence xy =ab
9x5=45
8
x = -7 ±3i
(x+7)^2+9=0
Subtract 9 from each side
(x+7)^2+9-9=0-9
(x+7)^2=-9
Take the square root of each side
sqrt((x+7)^2) = ±sqrt(-9)
We know sqrt(ab) = sqrt(a) sqrt(b)
x+7 = ±sqrt(-1) sqrt(9)
We know that sqrt(-1) is the imaginary number i
x+7 = ±i *3
x+7 =±3i
Subtract 7 from each side
x+7-7 = -7 ±3i
