Question

An illustration shows two parallel slanting lines m and l intersecting a vertical line k. The angles formed at the intersection of lines l and k are 1, 2, 4, and 3. The angles 1 and 4 are opposite to each other while angles 2 and 3 are opposite to each other. The angles formed at the intersection of lines m and k are 5, 6, 8, and 7. The angles 5 and 8 are opposite to each other while angles 6 and 7 are opposite to each other.

If m∠6=140° , what is m∠7 ?

140°

40°

180°

50°

Answer 1

180°

Answer 2

check again and provide evidence

Answer 3

Apologies for the mistake in my previous response. Let's reconsider the given information.

Angle 6 and angle 7 are opposite angles, which means they have the same measure.

Since m∠6 is given as 140°, it follows that m∠7 must also be 140°.

Therefore, the correct answer is 140°.
