Answer:
Alternate Interior Angles
Step-by-step explanation:
Angle 3 and angle 6 are inside the parallel lines and are opposite sides of the transversal line so, it'd be alternale interior angles.
Place each triangle in a fraction (side over side), and set each equal to each other.
6/9 = x/15
Isolate the x, cross multiply
6(15) = 9(x)
Simplify.
90 = 9x
Isolate the x, divide 9 from both sides
90/9 = 9x/9
x = 90/9
x = 10
Find the scale factor, find out what number is being multiplied to make the measurements become from one number to the other. Divide one of the larger triangle's sides with the smaller.
15/9 = 1.67 (rounded).
The scale factor is ~1.67
hope this helps
Answer:
Option D is correct
Step-by-step explanation:
-4(3x/2 - 1/2) = -15
<=>
-4*3x/2 + (-4)*(-1/2) = -15
<=>
-6x + 2 = -15
