Pretty sure it would be A
Answer:

Step-by-step explanation:
If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.
Use formula to find the coordinates of the point Q:

In your case, P(-2,7) and R(1,0), then

Answer:
∠ BXC = 70°
Step-by-step explanation:
∠ XBC and ∠ AXY are corresponding angles and are congruent, then
∠ XBC = 55°
Since XB = XC , then Δ XBC is isosceles and the 2 base angles are congruent.
∠ BXC = 180° - (55 + 55)° ← angle sum of triangle
∠ BXC = 180° - 110° = 70°
