Answer:
∠7 = 34°
Step-by-step explanation:
Since a and b are parallel lines then
∠3 and ∠7 are corresponding angles and congruent, so
∠7 = ∠3 = 34°
incoorect Step-by-step explanation:
Supplementary Angles two angles that sum up to 180°
the other two sides are that and the other side is 70
Answer:
similar; RYL by SAS similarity
Step-by-step explanation:
Side RL Is congruent to side RH and side RY is congruent to side RA by a scale factor of 3.5. and we know thank angles LRY and HRA are congruent by the reflexive property. So the two triangles are congruent by Side-Angle-Side similarity.
Answer:
Complementary angles.
Step-by-step explanation:
Notice that and , by given.
, by sum of angles.
, by supplementary angles definition.
Which means,
Therefore,, in other words, angles a and b are complementary by definition.
