R S Aggarwal and Veena Aggarwal Solutions for Exercise 1: EXERCISE 7A

Define the following term:

Supplementary angles

Find the complement of the following angle:

$16°$

If the complement of the following angle is $k°$ then find $k$:

$90°$

If the supplement of $42°$ is $x°$, then find the value of $x$.

If the supplement of the angle $90°$ is $x°$, then find the value of $x$.

If the supplement of $124°$ is $k°$, then find the value of $k$.

If the angle whose complement is one third of its supplement is $x°$, then find the value of $x.$

 Find the value of $x$ for which the angles $\left(2x-5\right)°$ and $\left(x-10\right)°$ are the complementary angles.
