Answer:
The correct answer is option C
They are complementary angles
Step-by-step explanation:
From the figure we can see two angles <ABC and <LMN,
<u>To find the correct option</u>
From figure we get,
m<ABC = 20°° and m<LMN = 70°
m<ABC + m<LMN = 20 + 70 = 90°
Therefore <ABC and <LMN are complementary angles
The correct answer is option C
They are complementary angles

Answer:
P(A and B) = 7/80
Step-by-step explanation:
The given values of the probabilities of the different events are;
P(A) = 7/20
P(B) = 7/20
P(A or B) = 49/80
P(A and B) = Required
We have by probability theory for any event;
P(A or B) = P(A) + P(B) - P(A and B)
Therefore;
P(A and B) = P(A) + P(B) - P(A or B)
Plugging in the values gives;
P(A and B) = 7/20 + 7/20 - 49/80 = 7/80
∴ P(A and B) = 7/80
