Answer:
corresponding angles
Step-by-step explanation:
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.
The picture in the attached figure
we know that
a) <span>
∠1 and ∠5are congruent-----> by corresponding anglesb) </span>∠3 and ∠8------> supplementary angles (∠3 + ∠8=180°)
<span>are not congruent
c)</span>∠6 and ∠4------> supplementary angles (∠6 + ∠4=180°)
are not congruent
d) ∠8 and ∠2------> supplementary angles (∠8 + ∠2=180°)
are not congruent
e) ∠4 and ∠7-----> supplementary angles (∠4 + ∠7=180°)
are not congruent
I hope this helps you
1)
-1-5/6=-6/6-5/6= -11/6
2)
-27/21-7/21=-34/21
3)
-2+26/7= -14/7+26/7 =12/7
600×3.5%=21. As a result, there are 21 phones that likely to be defective. Hope it help!
