Mathematics

If an angle is half of its complement, find the measure of angles.


SOLUTION
Sum of complementary angles = $$90^{0}$$
Let on angle = $$x^{0}$$
Then second angle = $$\frac{x}{2}$$
$$x+\frac{x}{2}=90^{0}$$
$$\Rightarrow \frac{3x}{2}=90^{0}$$
$$\Rightarrow 3x=90^{0}*2=180^{0}$$
$$\Rightarrow x=60^{0}$$
One angle = $$60^{0}$$
and the other angle = $$\frac{60}{2}=30^{0}$$
Angles are $$30^{0},60^{0}$$
