question number 25

Answer 1

please don't leave

Answer 2

please tell me you know how to do this :"{

Answer 3

NO!!!!!!!!!!!!!!!!!!!

Answer 4

Two sum of the two angles must be 180 degrees, agreed?

Answer 5

yes but aren't they complementary?

Answer 6

Further, because they are equal, they must both be 90 degrees, yes?

Answer 7

? but what about the 96?

Answer 8

why is it x + 96?

Answer 9

right, it must be that
x + 96 = 90

Answer 10

hence, what is x?

Answer 11

-6

Answer 12

yes

Answer 13

but how do you solve it? aren't they complementary angles?

Answer 14

Call then both A. We know that A + A = 180
i.e,
2A = 180
hence
A = 90

That's the answer.

Answer 15

why would they write x + 96? no purpose?

Answer 16

to test your resolve in solving this. the fact that it confused you means that there's some work to be done here to make you apply the basic principles are work.

Answer 17

but also you can see it's part of a series of question where you find angles and then have to solve a simple algebraic equation. this is just another variation on that theme.

Answer 18

ok, content?

Answer 19

no :"{ I answered Number 26 correctly by adding 20 and 24, which is 44x. i also added -1 and 5 to get 4
then i got
44x + 4 = 180
44x = 176
x = 4
then i plugged it into 20x + 5
and got 85

Answer 20

but I didn't know why i couldn't do it for number 25

Answer 21

For number 25,
(x + 96) + (x + 96) = 180
agreed, so far?

Answer 22

yes

Answer 23

Now solve for x.

Answer 24

2x + 192 = 180
subtract 192
2x = -12
divide by 2
x = -6

Answer 25

yes

Answer 26

OH!!!!! I'M A flutterING IDIOT!!!!!

Answer 27

thanks I understand

Answer 28

I need way more practice on this
