Answer:
x = 72 , y = 108
Step-by-step explanation:
2x and 
are adjacent angles on a straight line and sum to 180° , that is
2x + = 180 ( multiply through by 2 to clear the fraction )
4x + x = 360
5x = 360 ( divide both sides by 5 )
x = 72
--------------------------
= 
= 36
and 
are vertically opposite and are congruent , then
= 36 ( multiply both sides by 3 )
y = 108
Divide the top one from the bottom one
Answer:
There are 2 complex roots:
3 - 4i, 3 + 4i.
Step-by-step explanation:
x^2 - 6x + 25 = 0
Using the quadratic formula:
x = [-(-6) ± √(-6)^2 - 4*1*25)] / 2
= (6 ± √-64)/2
= 3 ± 8i/2
= 3 ± 4i
