Planes X and Y are perpendicular to each other
Points A, E, F, and G are points only in plane X
Points R and S are points in both planes X and Y
Lines EA and FG are parallel
The lines which could be perpendicular to RS are EA and FG.
Step-by-step explanation:
Actually a 30, 40, 50 triangle is just scaled ip 3, 4, 5 triangle, which is a well known right angled triangle.
Let's named wholesale price with variable x.
The appropriate equation is
1.6 x + 0.75 = 18.75 => 1.6x = 18.75 - 0.75 => 1.6x = 18 => x= 18/1.6
x= 11.25$ The wholesale price is 11.25$
Good luck!!!!
Answer:
y = 13
Step-by-step explanation:
If it's a parallelogram then its consecutive angles are supplementary (add up to 180°).
6x - 12 + 132 - x = 180°,
5x + 120 = 180
5x = 60
x = 12
6x - 12 = 6(12) - 12 = 72 - 12 = 60
Parallelogram, opposite angles are equal
so
6y + 18 = 6x - 12
6y - 18 = 60
6y = 78
y = 13
