Can someone help me with this question

Mathematics
1 answer:
exis [7]3 years ago
5 0

Answer:

Angle A + Angle B + Angle C = 180° (LP)

3x+5 + 5x-18 + 7x-2 = 180

3x +5x + 7x = 180 +15

15x = 195

x=195/15

x=13

Angle A: 3x + 5 = 3 x 13 + 5 = 44

Angle B: 5x - 18 = 5 x 13 - 18 = 47

Angle C: 7x - 2 = 7 x 13 - 2 = 89

4. DE is the perpendicular bisector of JL. Which statement must be true?
ZanzabumX [31]

Since DE is the perpendicular bisector of JL.

The perpendicular bisector is a line that divides a line segment into two equal parts. It also makes a right angle with the line segment. Each point on the perpendicular bisector is the same distance from each of the endpoints of the original line segment.

Since, a perpendicular bisector is a line that divides a line segment into two equal parts.

So, JK=KL. (which is not given in the option)

Since ED is a perpendicular bisector. So, each point on ED is the same distance from the endpoints of line segment JL.

So, EJ=EL.

Therefore, Option 1 is the correct answer.
