Answer:
Step-by-step explanation:
The scale factor of dilation of triangle ΔOPQ, S.F. = 3
The center of dilation = Point <em>Q</em>
Therefore;
The length of the segment, = 3 × The length of the segment,
Similarly;
By Pythagoras theorem, we have;
.
x = 3
7 + 6x - 4 = 3x - 9 + 7x
6x -3x - 7x = -9 - 7 + 4
-4x = -12
-4x/-4 = -12/-4
The answer is 4 and x-1
y= 4
y=x-1
1,200
1020 divided by 0.85= 1200
18/90=9/x and to find x use proportion so first 90*9=18x and 810=18x and x-45
