Answer: 7
Answer:
option a
Step-by-step explanation:
2 lines are said to be parallel when they don't intersect each other & they won't meet each other if the distance ( which separates both the lines intersecting each other ) is perpendicular to both the lines.
Here in the figure AC is perpendicular to both AB & CD. Hence AB || CD. Taking BC as transversal , m(2) = m(4) = 35°
X⁴-13x²+36
(x²-4)(x²-9)
x²=4. | x²=9
x=√4. |x=√9
x=2. |x=3
27x³-8=0
x³=8/27
x=2/3
