Question 61 Mark

Find the supplement of the following angles. $\frac{3}{5}$ of a right angle.

Answer

Two angles whose sum is $180^\circ $ are called supplementary angle. $\frac{3}{5}$ of a right angle $\Rightarrow\Big(\frac{3}{5}\times90\Big)=54^\circ$ Supplement of $\frac{3}{5}$ of a right angle $= (180 - 54)^\circ = 126^\circ .$

Question 81 Mark

Find the comlement of the following angle. $\frac{2}{3}$ of a right angle.

Answer

Two angles whose sum is $90^\circ $ are called complementary angle. $\frac{2}{3}$ of a right angle $\Rightarrow\Big(90\times\frac{2}{3}\Big)^\circ=60^\circ$ Complement of $\frac{2}{3}$ of a right angle $= (90 - 60)^\circ = 30^\circ .$
