(2x)°+54°=90°
left parenthesis 2 x right parenthesis degrees plus 54 degrees equals 90 degrees

(2x)°+21°=90°
left parenthesis 2 x right parenthesis degrees plus 21 degrees equals 90 degrees

(2x)°+54°=180°
left parenthesis 2 x right parenthesis degrees plus 54 degrees equals 180 degrees

(2x)°+21°=180°
left parenthesis 2 x right parenthesis degrees plus 21 degrees equals 180 degrees

Answer 1

The correct equation to solve for x is (2x)° + 21° = 180°.

Answer 2

the correct answer is (2x)°+54°=180

Answer 3
