What is the name of an interior angle of a triangle that shares a side and a vertex with an exterior angle of the triangle?
a. exterior angle
b. adjacent interior angle
c. remote interior angle
d. alternate interior angle

Correct option is B that is Adjacent interior Angle.

Step-by-step explanation:

Given: A triangle

          An exterior angle of the triangle.

We need to tell name of interior angle which has a side and a vertex of the exterior angle of the triangle.

Since, Here we have a common vertex and a common arm of angle with exterior angle. Which means it is an adjacent angle with exterior angle.

Also it is interior angle of triangle.

Thus, Correct option is B that is Adjacent interior Angle.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

5x+10 is the correct one

hope this
