5.3 I'm guessing
sorry if it isn't correct
Answer:
I think 2 points
Step-by-step explanation:
I may be wrong bc I suck at algebra. literally who is gonna use algebra ever?
Step-by-step explanation:
By Sine Rule, 13/sin96° = x/sin25°.
Hence, x = 13sin25°/sin96° = 5.5.
ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8
Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28
So there are no real number solutions, yet there are complex numbers solutions.
Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
