How many triangles can be drawn having its angles as `53^(@)`, `64^(@)` and `63^(@)`? Give reason for your answer.

Text Solution

AI Generated Solution

To determine how many triangles can be drawn with angles of \(53^\circ\), \(64^\circ\), and \(63^\circ\), we will follow these steps: ### Step 1: Check the Angle Sum Property The first step is to verify if the sum of the given angles equals \(180^\circ\), which is a requirement for the angles of a triangle. \[ 53^\circ + 64^\circ + 63^\circ \] ...
