# Beginner Vector Geometry #2

Geometry Level 2

There are two vectors, $$\overrightarrow{x}=(3,~7)$$ and $$\overrightarrow{y}=(-8,~9)$$.

Find the value of $$\overrightarrow{x}\cdot\overrightarrow{y}$$.

Notation: $$\overrightarrow{a}\cdot\overrightarrow{b}$$ denotes the inner product of the two vectors $$\overrightarrow{a}$$ and $$\overrightarrow{b}$$.

This problem is a part of <Beginner Vector Geometry> series.
