Pls help! will give brainlist!

Since this is a transversal, I am using certain rules to figure this out.

For example, angles 1 & 2 should equal 180 when added together, in the same way angles 11 & 12 should do the same thing!

Therefore, since angle 1 is 140°, angle 2 should be 40°, to complete it. This is the same for the other side!

Angle2: 40

Angle11: 60

Step-by-step explanation:

ang1+ang2=180 (Linear pair)

140+ang2=180

ang2=40

ang2+ang9+ang11=180 (angle sum property)

40+80+ang11=180

ang11=180-120

ang11=60

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
