Question

what is the measurement of angle 2?

Answer 1

Picture?

Answer 2

okay

Answer 3

Ok, what do we know about this 125 degree angle to the far left?

Answer 4

that is supplementary and that the other side is 55 degrees

Answer 5

Sorry, let me take a different approach.

Answer 6

We can see that angle 2 is part of a triangle.

Answer 7

yes

Answer 8

I gotta go so sorry that I wasn't much of a help : /

Answer 9

Angle 2 + 2 other angles = 180 degrees

Answer 10

thats fine thanks @mathwizzard3 and yes so angle 2 +angle 3 + the right angle = 180 degrees

Answer 11

Right!

Answer 12

So, back to that 125 degree angle.

Answer 13

look at lines a and b and their transversal

Answer 14

ok

Answer 15

Which angle should be congruent to the 125 degree angle?

Answer 16

Well, first off, by the corresponding angles theorem, angle 1, right?

Answer 17

angle 1 i think should be congruent to 125 degree angle

Answer 18

Yup!

Answer 19

So, as you can see, 2 is supplementary to 1, right?

Answer 20

So, 2 should be 55

Answer 21

so angle 2 would 55 degrees

Answer 22

And now we can also find angle 3 if we wanted to

Answer 23

Or any other angle here. See how useful geometry is?

Answer 24

Do you understand now?

Answer 25

so angle 3 would be 35 degrees

Answer 26

Yup!

Answer 27

yes thank you so much my last question was thinking way to hard to find that

Answer 28

No problem! *puppy fistbump*

Answer 29

haha
