A triangle was dilated. One point on the original triangle was (2, -3). The same point on the new triangle was (3, -4.5). What was the scale factor? * 15 points
a : .5
b : .75
c :1.5
d : 2/3

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
