Since you already know BC is 23inches, you can minus it from 83 inches first.
Next, you have to realise that since angle ABC and angle ACB are both 65 degrees and equal, the triangle is an isosceles triangle it means that AC is equals to BC.
Thus, it means that you can divide (83-23) by 2, which is 30 inches
Answer: SAS
Step-by-step explanation:
Here ABC is a triangle, In which angle BAC is bisected by line AR where, 
.
Thus in triangles ABR and ACR,
AB= AC ( given)
Therefore 
( by the property of angle bisector)
And, 
(reflexive)
Thus by SAS postulate,
△ABR ≅ △ACR.
Therefore, Option D is correct.
(8x + 7) - (2x - 3)
(8x + 7) + (-2x + 3)
combine like terms
8x - 2x and 7 + 3
6x + 10
