Question

What is the value of x in the figure?

Answer 1

what figure?

Answer 2

@JesseJ0906

Answer 3

what have you tried?

Answer 4

Must be 96 degrees, because you have an isosceles triangle, so angle next to it is also 42, and the remaining angle is 96 degrees (as all 3 angles must add up to 180). Angle x is the vertical angle, so it is also 96 degrees. Vertical angles are equal.

Answer 5

When two sides of a triangle are equal, the angles opposite them are equal.

Answer 6

ive tried the options are 96º
42º
106º

Answer 7

So you have two base angles equal in that upper triangle.

Answer 8

@megan11 Do you see in the upper triangle, the two base angles of the isosceles triangle?

Answer 9

two angles whose sum is 84 degrees; remaining angle is 180 - 84 = 96

Answer 10

Therefore, the opposite angle is also 96 as it is a vertical angle to the 96-degree angle in the upper triangle.

Answer 11

every triangle must have
180 degrees
since the given was 2 congruent angles
isoc triangle

Answer 12

@megan11 Easyaspi314 has given you the answer, should thank him

Answer 13

lol

Answer 14

@skullpatrol Thanks.

Answer 15

:)

Answer 16

um. i was getting there. i was finishing my exam.

Answer 17

is that a question on your exam?

Answer 18

no. it was a pre test

Answer 19

but you should use the pre test as a real test of your ability, no?

Answer 20

so you don't get any nasty surprises on the actual exam

Answer 21

@megan11 are you still there?

Answer 22

@skullpatrol

When a question is posted, how is one to know if that is an exam question? Any clues to look for?

Answer 23

@Easyaspi314 usually a test question uses a lot of different ideas, and tests the student's ability to combine them properly.

Answer 24

Still, no way of really knowing.

Answer 25

@Easyaspi314 but we can't be held responsible for students trying to use this web site as a source during a test, that is the teacher's duty, right?

Answer 26

absolutely.

Answer 27

yall. i wasn't getting graded on the pre-test. i go to an online school so i only meet with my teachers a few times a week. she encourages us to get help if we are stuck on a problem for more then and hour and this question i was. but i knew how to do it i just forgot. i only wanted to be guided.

Answer 28

They are only hurting themselves by cheating, they will find out in higher level math courses that the skills needed to keep up with the work load are just not there...

Answer 29

...and it will be too late by then :(

Answer 30

@megan11 you learn a lot by trying to get yourself un-stuck

Answer 31

Learning and understanding is a very personal activity, good problem solvers learn from their mistakes.

Answer 32

I did not cheat it was a pre-test. Your putting me down and it ind of hurts. i didn't realize i couldn't ask for help. @skullpatrol

Answer 33

I'm not saying you cheated, I'm just talking about the learning and understanding process :)
