Answer:
k = 11
Step-by-step explanation:
let the points be A(-2,5), B(2,8), C(6,K).
for the points to be collinear slope of line AB maust be equal to line BC.
slope of line AB =
slope of line BC =
therefore
therefore k = 8 + 3
k = 11

Answer:
Step-by-step explanation:
To use the SAS similarity theorem, you must show proportionality between corresponding sides, and congruence of the angle between them.
The answer shown above is the only answer choice that mentions an angle.

<em>Comment on other choices</em>
Choice B shows the three sides are proportional, so would be useful if the SSS similarity theorem were to be invoked. It isn't helpful for the using the SAS similarity theorem.
Choices C and D get the proportion statements wrong.
