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

Question

Answer:
:
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).
