Question 84
An angle is smaller than its supplementary angle by 70°. What is the measure of the angle?
Solution
Let the angle = $$\theta$$
Its supplementary angle = $$(\theta + 70$$°$$)$$
Sum of an angle and its supplementary angle = 180°
=> $$\theta + (\theta + 70$$°$$) = 180$$°
=> $$2 \theta = 180$$°$$ - 70$$°$$ = 110$$°
=> $$\theta = \frac{110}{2} = 55$$°
