Step-by-step explanation:

\huge\underbrace\blue{Answer:-}

The angles of triangle are=(x+21)°,x°,(2x-45)°

as we know

\large\blue{\boxed{The sum of three angles=180°}}

according to formula,

(x+21)+x+(2x-45)=180

=>x+21+x+2x-45=180

=>4x+(-24)=180

=>4x-24=180

=>4x=180+24

=>4x=204

=>x=204/4=51

=>x+21=51+21=72

=>2x-45=2×51-45

=102-45=57°

hence the angles are 72°,51°,57°

Answer:

x+21°+x+2x-45=180°(angle sum property)

4x-24=180°

4x = 180+24

4x=204

x=204/4

x=51
