 4 x degrees plus 3 degrees is equal to 90 degrees - no response given

4x°−3°=90°
4 x degrees minus 3 degrees is equal to 90 degrees - no response given

2x°−3°=90°
 2 x degrees minus 3 degrees is equal to 90 degrees - incorrect

2x°+3°=90°

1 answer

Complementary angles are two angles whose measures add up to 90 degrees. Given the measures of the angles as \((x-6)°\) and \((3x+3)°\), we can set up the equation:

\[ (x - 6) + (3x + 3) = 90 \]

Now, let's simplify this:

  1. Combine like terms: \[ x + 3x - 6 + 3 = 90 \] This simplifies to: \[ 4x - 3 = 90 \]

  2. Finally, we can express this as: \[ 4x - 3° = 90° \]

So the correct simplified equation for the angles is:

\[ 4x - 3° = 90° \]

Hence, the correct choice is:

4x°−3°=90°
