Step 1: Understanding the Concept:
In a Cartesian coordinate system, a point is represented by an ordered pair \((x, y)\). The x-coordinate is called the abscissa, and the y-coordinate is called the ordinate.
Step 2: Detailed Explanation:
The given point is \((-6, -8)\).
Here, the x-coordinate (abscissa) is -6.
The y-coordinate (ordinate) is -8.
The question asks for the ordinate of the point.
Step 3: Final Answer:
The ordinate of the point (-6, -8) is -8.
Given $\triangle ABC \sim \triangle PQR$, $\angle A = 30^\circ$ and $\angle Q = 90^\circ$. The value of $(\angle R + \angle B)$ is
