Answer:
Step-by-step explanation:
Hi,
We know that
P(A or B)=P(A)+P(B)-P(A and B)
so P(B)= P(A or B) - P(A) + P(A and B)
so
P(B) = 0.5 - 0.4 + 0.2 = 0.3

Answer:
∠KXN and ∠QXT
Step-by-step explanation:
The measure of each angle is the difference of the scale values that the rays intercept. (The same scale needs to be used for each ray.) Of course, complementary angles have a sum of 90°.
Here, we'll refer to angle aXb as "ab".
NP = 95 -35 = 60
PQ = 35 -20 = 15 . . . not complementary to NP
__
KN = 165 -95 = 70
QT = 20 -0 = 20 . . . complementary to KN ⇒ your answer
__
JK = 180 -165 = 15
PQ = 35 -20 = 15 . . . not complementary to JK
__
JK = 15
NK = KN = 70 . . . not complementary to JK
