Question

te measurement of one angle of a right triangle is 61 degree. what is the measurement of the third angle?

Answer 1

Let's call our unknown angle x .

We know that the sum of the three interior angles of a triangle is 180°

This way,

$\begin{gathered} x+90+61=180 \\ \rightarrow x=180-90-61 \\ \rightarrow x=29 \end{gathered}$

We get that the third angle measures 29°
