Answer 1

Step-by-step explanation:

Correct Question:-

Two angles of a triangle measures 50° and 30° respectively. Find the third angle.

Solution:-

Let the angle=x

As we know that in a triangle

${:}\longrightarrow$$\large{\boxed{the\:sum\:of\:angles=180}}$

${:}\longrightarrow$$50+30+x=180$

${:}\longrightarrow$$80+x=180$

${:}\longrightarrow$$x=180-80$

${:}\longrightarrow$${\underline{\boxed{\bf{x=30°}}}}$
