For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.

4
Step-by-step explanation:
Answer:
The correct option is d
d) (√2 - √6)/4
Step-by-step explanation:
The term given in the question is:
cos (-7π/12)
Solve the term by using scientific calculator:
cos (-7π/12) = (1 / 2√2) - (√3 / 2√2)
Mulitplying and dividing both terms on the right hand side of equality with 2√2:
(1 / 2√2) - (√3 / 2√2) = (1 / 2√2)(2√2 / 2√2) - (√3 / 2√2)(2√2 / 2√2)
(1 / 2√2)(2√2 / 2√2) - (√3 / 2√2)(2√2 / 2√2) = 2√2 / (2√2)² - (2√2)(√3) / (2√2)²
2√2 / (2√2)² - (2√2)(√3) / (2√2)² = 2√2 / (4)(2) - 2√6 / (4)(2)
2√2 / (4)(2) - 2√6 / (4)(2) = √2/4 - √6/4
√2/4 - √6/4 = (√2 - √6)/4
P= 2I + 2W, -2I -2W
Solve for P by Simplifying both sides of the equations, then isolating the variable.
