Answer:
Step-by-step explanation:
Distinct ways in which Barry can arrange the wooden shaped blocks is calculated from the permutation expression
4 permutation 3 =
P(n,r)=P(4,3) =4! ÷ (4−3)! = 24
Billie's distinct ways of seeing the arrangement would be 4 permutation 2
P(n,r)=P(4,2) =4! ÷ (4−2)! = 12
Answer:
well the first one is congruent to 120 because it is alternate interior which means its in between the other two lines
the second one is 60 degrees
Step-by-step explanation:
the second one its 60 degrees cause e and d make a line which is a straight line which is 180 degrees now subtracted 180 and 160 and you get 60 so yeah
i hope this helped
Answer:
The equation of the perpendicular line is 2 x + y + 1 =0
Step-by-step explanation:
<u><em>Step(i) </em></u>:-
Given equation of the line 2y = x - 18
x - 2y - 18 =0
The equation of the perpendicular line to the given line
b x - ay +k=0
-2 x - y + k =0 this line is passing through the point ( 0 , -1)
⇒ 0 -(-1) + k=0
⇒ 1+k =0
⇒ k = -1
<u><em>Step(ii):-</em></u>
The equation of the line is perpendicular to the line
-2x - y - 1 =0
2 x + y + 1 =0
<u><em>Conclusion:-</em></u>
The equation of the perpendicular line to the given line 2 x + y + 1 =0
