If sine (theta) = 4/7 then theta is found by:
arc sine (4/7) = theta
theta = 34.85 Degrees
cosine (34.85) = 0.82065
Answer:
<em>If two lines are cut by a transversal such that alternate exterior angles are congruent, then the lines are parallel.</em>
Step-by-step explanation:
Start by stating that the given angles are congruent.
Call the angle vertical to angle 1 "angle 3."
Then angle 3 and angle 1 are congruent by vertical angles.
Angle 3 and angle 2 are congruent by transitive congruence of angles.
That makes lines u and v parallel by congruent corresponding angles of two lines and a transversal.
Answer
You can prove the following theorem:
<em>If two lines are cut by a transversal such that alternate exterior angles are congruent, then the lines are parallel.</em>
