Question

Which relationship is always correct for the angles p, q, and r of triangle ABC?
p + r = q
p + q + r = 180 degrees
p + q + r = 90 degrees
q + r = p

Answer 1

Answer 2

i think its b

Answer 3

@texaschic101 @misty1212

Answer 4

B is incorrect.

Answer 5

can you explain why pls?

Answer 6

@StudyGurl14 what about d?

Answer 7

Answer 8

if pqr are the 3 angles of a triangle, then yes .. they add up to 180 always (assuming euclidean geometry of course)

Answer 9

wait... so b is correct?

Answer 10

but then theres a picture .... so disregard that

Answer 11

lol

Answer 12

since p is not part of the triangle angles proper ... b is not correct

consider that the angle related to p in the triangle is: 180-p, since it forms a straight line

now; add up those angles

(180-p)+q+r = 180

Answer 13

but what is p? i dont have any numbers

Answer 14

solve the relationship ....

Answer 15

how would i do that? im kinda confused :/

Answer 16

does x+p = 180?

Answer 17

yes

Answer 18

does q+r+x = 180?

Answer 19

yes

Answer 20

if 2 things are equal to another, then they are equal to each other

x+p= 180

x+q+r = 180

x+p = x+q+r

..... what can we conclude?

Answer 21

180 + 180 = 360

Answer 22

no, we are solving for p

Answer 23

p would be 90?

Answer 24

does:

x+n = x+n ??

if so, then

x+(p) = x + (q+r)
n n

Answer 25

ohh

Answer 26

since n=n ... p=n ... p=q+r

Answer 27

wait a sec pls

Answer 28

so then i was right on my second guess, the answer is d?

Answer 29

if your guessing, then who knows ... but since we just proved it, yes :)

Answer 30

Answer 33

thx

Answer 34

i might be attending to my own real life issues ... but if im available ill see what i can do
