Question

Find all the angles of the following triangle. [3 MARKS]

Answer 1

Each angle: 1 Mark

The three angles in the given triangle are x, 2x and 3x.
For any triangle,
Sum of all the angles = 180${}^o$
Or, x + 2x + 3x = 180${}^o$
Or, 6x = 180${}^o$
Or x = $\frac{{180}^o}{6}$ = 30${}^o$

The angles of the triangle will be 30${}^o$(x), 60${}^o$(2x) and 90${}^o$(3x).
