I need help with geometry
olchik [2.2K]

Answer:

m<1=?

m<2=4x-20..........(1)

m<4=3x-11.............(2)

Step-by-step explanation:

we have

  • m<2=m<4(corresponding angle of parrelelogram are equal)
  • 4x-20=3x-11
  • 4x-3x=20-11
  • x=9

again.we have

<1+<2=180(co-interior angle)

<1=180-<2=180-(4×9-20)=180-16=164

Discuss the conditions under which P(A or B)= P(A) + P(B) is true
Andrews [41]
That condition is true if P(A) and P(B) are independent of one another. For example, if I was pulling marbles out of a bag, if I am replacing the marbles back after I pull one out, then P(A or B) = P(a)+P(B).
