What Us Mlt5 Explain How You Know class=

Sagot :

Answer:

  m∠5 = 75°

Step-by-step explanation:

Transversal 'a' crosses parallel lines 'l' and 'm' creating corresponding angles 1 and 5. Corresponding angles are congruent.

The measure of angle 1 is given as 75°. Congruent angle 5 will have the same measure.

  ∠5 = 75°

Additional comment

Angle 2 is an alternate interior angle with respect to transversal 'b' and angle 4. It is congruent to angle 4.

  ∠2 = 50°

Angles 1, 2, and 3 together form a straight angle of 180°. That means ∠3 is ...

  ∠3 = 180° -75° -50° = 55°
