Answer:
A dilation transformation is by shrinking or expanding the image by a scale factor x. To perform a dilation multiply the coordinates by the scale factor number given.
Step-by-step explanation:
Answer:
x = 20°
m∠A = 125°
Step-by-step explanation:
Angle A and B are alternate interior angle, so they are the same:
4x + 45 = 6x + 5
4x + 40 = 6x
40 = 2x
x = 20
m∠A = 6(20) + 5
m∠A = 120 + 5
m∠A = 125°
