Use the image to answer the question. If m∠6=140° , what is m∠7 ? (1 point) Responses 140° 140 degrees 180° 180 degrees 50° 50 degrees 40°

1 answer

To determine the measure of angle \( m∠7 \), we need to use the information given about \( m∠6 = 140° \).

Assuming that angles 6 and 7 are supplementary (which means they add up to 180°), we can set up the equation:

\[ m∠6 + m∠7 = 180° \]

Substituting \( m∠6 \) into the equation:

\[ 140° + m∠7 = 180° \]

Now, subtract \( 140° \) from both sides:

\[ m∠7 = 180° - 140° \]

\[ m∠7 = 40° \]

Therefore, \( m∠7 \) is \( 40° \). The correct response is 40°.
