Given: ab is the perpendicular bisector of ik.
which statement can you conclude is true from the given information?
a. aj=bj
b. angle iaj is a right angle
c. ij=jk
d. a is the midpoint of ik

The correct answer is C. IJ = JK

Step-by-step explanation:

⇒ AB divides the line segment IK in two equal parts i.e. IJ = JK and the angle formed at the point of intersection J is 90° ⇒ ∠AJI = 90°.

∠AJI + ∠AIJ + ∠IAJ = 180° ( But ∠AJI = 90° )

∠AIJ + ∠IAJ = 90° ⇒ ∠IAJ < 90°

So, ∠IAJ is not a right angle.

Hence, we conclude the correct statement is IJ = JK

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
