Options: (50)^1/2, (65)^1/2, (105)^1/2, (145)^1/2 last sentence options: 55.21, 85.16, 105.26, 114.11

Step-by-step explanation:

Vertices of ΔABC are,

A(-3, 6), B(2, 1) and C(9, 5)

Use the formula to get the distance between two points and,

Distance =

By using the formula,

AB =

     = units

BC =

     = units

AC =

     =

Use cosine rule to find the measure of ∠ABC.

AC² = AB² + BC²- 2(AB)(BC)cos(B)

145 = 50 + 65 - 2(√3250)cosB

cos(B) =

          = -0.26312

B =

B = 105.26°
