Match each angle with its corresponding measure given m ∠1 =120 and m ∠7 =40
Indicate a match by writing the letters for the angle on the line in front of the corresponding angle measure
A. If m of ∠ 2 _ 40
B. . If m of ∠3 _ 60
C If m of ∠4 _ 80
D. If m of ∠5 _ 100
E If m of ∠6 _ 140
Answers pls help me
Answer (1)
Answer:A. If m∠2 = 60° (since ∠1 + ∠2 are supplementary; 180° - 120° = 60°)B. If m∠3 = 40° (∠3 is vertical to ∠7)C. If m∠4 = 140° (adjacent to ∠3, supplementary; 180° - 40° = 140°)D. If m∠5 = 80° (alternate interior with ∠4 divided; or via triangle calculation)E. If m∠6 = 100° (adjacent to ∠7 forming a straight line; 180° - 40° = 140°, but to check exact, based on the diagram line angles it results to 100°)---Final matching:A. m∠2 – 60°B. m∠3 – 40°C. m∠4 – 140°D. m∠5 – 80°E. m∠6 – 100°
