Respuesta :

<BAC is 35 because "the exterior angle of a triangle is equal to the sum of the interior angles at the other two vertices" or 180-120= 60 so <BCA is 60 and angles in a triangle add to 180 so 180-(85+60)=35

Answer:

The answer is 35

Step-by-step explanation:

It is 35 because "the exterior angle of a triangle is equivalent to the sum of the interior angles at the other two points" or 180-120= 60 so <BCA is 60 and angles in a triangle sum to 180 so 180-(85+60)=35

Btw I had help.
