Answer:
Tangent = opposite / adjacent
Tangent of 45º equals 1
Step-by-step explanation:
Answer:
B'(16,14)
Step-by-step explanation:
In square ABCD, A(2,7) C(8,1) D(2,1). First, find the coordinates of the vertex B. From the attached diagram you can see that CD=6 units and is parallel to the x-axis, AD=6 units and is parallel to the y-axis. So, B(8,7).
The origin O is the center of dilation, 2 is the scale factor. The rule of the dilation is
(x,y)→(2x,2y)
Thus,
B(8,7)→B'(16,14) (see attached figure).
Let the remaining angle be x
X+75=180( being straight angle)
Or x=180-75
.’. X= 105 is the ans
