As we can see in the shown figure:
1) I and J are parallel
2) I and g are perpendicular because we have constructed the steps to make the perpendicular to the line I
3) J and g are perpendiculars because I and J are parallel and I perpendiculars to g
Answer:
Step-by-step explanation:
∠ABC = ∠BCD { AB // CD; BC TRAVERSAL, alternate angles are equal}
∠ABC = 20
∠BCA = ∠BAC {angles opposite to equal sides are equal}
∠BCA = ∠BAC = x
x + x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80
The answer is 566m because 147 plus 147 and 136 plus 136 equals 566
Answer:
54
Step-by-step explanation:
9/12=x/12
9*12=108
108/2=54
Answer:
The lady is on the second door
Step-by-step explanation:
we have that
The sign on the first door reads "In this room there is a lady, and in the other one there is a tiger"
The sign on the second door reads "In one of these rooms, there is a lady, and in one of them there is a tiger."
so
The sign on the second door is true
The sign on the first door is true or false
Since one of these signs is true and the other is false, the sign in the first door must be false
therefore
The lady is on the second door
