@jim_thompson5910, you think you could help me?

jim_thompson5910 · Answer

all right angles are what number of degrees

anonymous · Answer

90%

jim_thompson5910 · Answer

90 degrees, good

jim_thompson5910 · Answer

so because 1 and 4 are right angles, they are 90 degree angles

jim_thompson5910 · Answer

so what does that mean

anonymous · Answer

wouldnt it be the last answer?

jim_thompson5910 · Answer

m < 1 + m < 4 = 90

90 + 90 = 90

180 = 90

is that true?

anonymous · Answer

Oh, no that's incorrect...

jim_thompson5910 · Answer

yep, so it can't be the last one

anonymous · Answer

So it would be the thirh since 90+90=180 ?

jim_thompson5910 · Answer

that would be true IF we knew that both angles 3 and 5 were both 90 degrees

but we don't know this

jim_thompson5910 · Answer

or IF we knew that they were both supplementary, but again, we don't know this

anonymous · Answer

I'm so confused..

jim_thompson5910 · Answer

you agree that angles 1 and 4 are both 90 degrees right?

anonymous · Answer

correct.
OH! i think its the second choice!

jim_thompson5910 · Answer

yep all right angles are congruent

anonymous · Answer

I get it now, Thanks :) !
