True. Both denominators (5x and 12x) divide into 60x without a remainder.
Given:
Line segment XY is located at X(2, 6) and Y(4,8).
The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4).
To find:
The coordinates of X'
Solution:
If a figure dilated by a scale factor k with a center of dilation (a,b), then the rule of dilation is:

The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4). So, the rule of dilation is




The coordinate of X are (2,6).



Therefore, the coordinates of X' are (7,8).
Answer:
a. 20°
Step-by-step explanation:
The external angle T is half the difference of the intercepted arcs:
(92° -52°)/2 = 40°/2 = 20°
∠ETR = 20°
9514 1404 393
Answer:
C. 39°
Step-by-step explanation:
The measure of the angle where the chords cross is the average of the measures of the subtended arcs.
x = (AB +CD)/2 = (28° +50°)/2 = 78°/2
x = 39°
