Answer:
(c) Pi/4
Step-by-step explanation:
3pi/4 = (3 x 180) / 4 = 135 degrees
135 degrees is equivalent to (180 degrees - 135 degrees) 45 degrees
45 degrees = Pi/4
Therefore, the reference angle of 3pi/4 is Pi/4
Thus, the correct option is (c) Pi/4
Make x=0 in the second equation, giving you y=-3. If you plug that in to the top equation you would get x-3(-3)=-19, x+9=-19,x=-28.
Answer:
Scaling is used to resize the dimension of a structure to fit the different platforms, like from structure to paper.
Step-by-step explanation:
To resize down-scale the dimension of a room, if the scale is 1/4 inches per foot, then the size of a 6x4 feet (width and length) room would be;
1/4 x 6 = 1.5 inches
1/4 x 4 = 1 inches
that is, 1.5 x 1 inch on paper when scaled down.
