Answer:
13. alternate interior
14. linear pair/ none of the above
15. vertical angles
16. corresponding angles
Step-by-step explanation:
Answer: 42.6% or you can round it to 43%
Step-by-step explanation:
Supplementary and adjacent.
Two angles are called supplementary when their measures add up to 180 degrees.
Adjacent angles are two angles that have a common vertex and a common side but do not overlap.
6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
