Calculate the size of unknown angles

see explanation

Step-by-step explanation:

In a parallelogram the opposite angles are congruent , then

2p - 50 = p + 10 ( subtract p from both sides )

p - 50 = 10 ( add 50 to both sides )

p = 60

Then

∠ E = ∠ I = p + 10 = 60 + 10 = 70°

consecutive angles sum to 180° , so

∠ L = ∠ K = 180° - 70° = 110°

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

you first to choose the points and then move from then as the slope you have
