84/7=12
The scale factor is 12 from triangle DCE to triangle BAC.
12(x)=156-x
12x=156-x
13x=156
x=12 (proving)
156-12=144
The answer is A) 144

Answer:
sin70° = x/6
Step-by-step explanation:
When we draw out our picture and triangle, we should see that our angle is on the ground 70°, the height <em>x</em> is across from the angle and is the vertical leg up, and that our hypotenuse is equal to 6:
sin70° = x/6
The second one i got (0,-2) first one i got (0,9)
