Let the boy be B and the girl be G
there are six possible outcomes
BGG, GBB, GBG, BGB, BBB, and GGG
therefore the probability of getting one boy and two girls is
also the probability of getting 3 girls is
Answer: 80 miles
Step-by-step explanation:
Step-by-step explanation:
Given :
1- cosA = 1/2
or, CosA = 1 -1/2
Therefore ; CosA = 1/2 = b/h
According to the Pythagoras theorem,
P = root under h^2 - b^2
= root under (2)^2 - (1)^2
= root under 4 -1
= root 3
Again,
SinA = P/h
= root 3 / 2
Answer:
∠6 = ∠8
∠2 = ∠6
Step-by-step explanation:
Lines 'p' and 'q' are the parallel lines and line 'l' is a transversal line intersecting these lines at two distinct points.
By the property of alternate interior angles,
∠3 = ∠5
By the property of vertically opposite angles,
∠6 = ∠8
By the property of corresponding angles,
∠2 = ∠6
graph of a linear equation is a line, two linear equations has no solution mean two lines has no intersect/common point, those two lines must be parallel
