What is the name of an interior angle of a triangle that is not adjacent to a given exterior angle of the triangle?
a. exterior angle
b. adjacent interior angle
c. remote interior angle
d. alternate interior angle

C. remote interior angle

Step-by-step explanation:

The angle between a side of a shape and the line extended from the next side is known as exterior angle.The angles that do not share a vertex (of a triangle) with the exterior angle is known as remote interior angles .The measure of the exterior angle and the sum of the two remote interior angles are equal.A pair of two interior angles that share a common side are  known as adjacent interior angles.The pair of angles that are formed on opposite sides of the transversal and inside the two lines are known as alternate interior angles.

Hence, the  name of an interior angle of a triangle that is not adjacent to a given exterior angle of the triangle is remote interior angle

So , correct option is C. remote interior angle.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
