Question

An angle is $56°$ more than its supplement. Then what is the measure of that angle

Answer 1

The sum of two supplementary angles is $180°$

let the angle be $x$

then, its supplement will $180-x$

according to question

$$\begin{gathered} \Rightarrow x=180-x+56 \\ \Rightarrow 2x=236 \\ \Rightarrow x=118° \end{gathered}$$
