Two sides of a triangle have lengths 6 and 17. Which expression describes the length of the third side? A. at least 11 and less than 23 B. at least 11 and at most 23 C. greater than 11 and at most 23 D. greater than 11 and less than 23

OpenStudy (anonymous):

hello?

OpenStudy (anonymous):

Sum of 2 sides of triangle is always greater than the third side. And absolute difference of 2 sides of a triangle is always less than the 3rd side. From that, 3rd side ia less than 6+17 = 23 and greater than 17-6=11. Option B.

OpenStudy (anonymous):

ok, thank you can u help me with one more?

OpenStudy (anonymous):

Oops! The answer would be D. Not B. Sorry.

OpenStudy (anonymous):

Yeah.. Sure! :)

i need help with 2 more

OpenStudy (anonymous):

Which three lengths CANNOT be the lengths of the sides of a triangle? A. 23 m, 17 m, 14 m B. 11 m, 11 m, 12 m C. 5 m, 7 m, 8 m D. 21 m, 6 m, 10 m

OpenStudy (anonymous):

Which three lengths could be the lengths of the sides of a triangle? A. 12 cm, 5 cm, 17 cm B. 10 cm, 15 cm, 24 cm C. 9 cm, 22 cm, 11 cm D. 21 cm, 7 cm, 6 cm

OpenStudy (anonymous):

For the 1st question, option D is the answer. Since, 21+6 = 27 and 21-7=14. Therefore, the 3rd side should be in btw 14 and 27.

OpenStudy (anonymous):

And Similarly, For the 2nd question.. it is option B.

OpenStudy (anonymous):

The folding chair can be set in different positions that change the angles formed by its parts. As angle 1 increases, how does the relationship change between the back of the chair and the front leg of the chair? A. As the measure of increases, the distance between the back of the chair and the front leg of the chair increases. B. As the measure of increases, the distance between the back of the chair and the front leg of the chair decreases. C. As the measure of increases, the distance between the back of the chair and the front leg of the chair remains constant.

OpenStudy (anonymous):

ur welcome

OpenStudy (anonymous):

that is the image url

OpenStudy (anonymous):

Option B.

OpenStudy (anonymous):

Yeah.. The answer is B.

OpenStudy (anonymous):

Which two statements contradict each other? I. lies on plane PQR. II. Point S lies on plane PQR. III. does not lie on plane PQR. A. I and II B. I and III C. II and III D. No two of the statements contradict each other.

OpenStudy (anonymous):

in between I. and Lies, is supposed PQ

OpenStudy (anonymous):

And in btw III. and does not?

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

Your statement III is not clear. Can you check it once, please?

OpenStudy (anonymous):

it supposed to be QS does not lie on plane PQR

OpenStudy (anonymous):

Good. The answe is C.

OpenStudy (anonymous):

II and III are contradictions.

OpenStudy (anonymous):

ok cool thank u so much, I hav one more and I'll be through, I really, really appreciate what ur doing for me thank you

OpenStudy (anonymous):

Thats Okay. :)

OpenStudy (anonymous):

A. AB<BC B. AC=FH C. BC<FH D. AC<FH

OpenStudy (anonymous):

do u see the problem

OpenStudy (anonymous):

Option D.

OpenStudy (anonymous):

Yeah.. It is a bit typical problem. So, took time for solving.

OpenStudy (anonymous):

ok, well, im through, if I need any thing else you will the first one I hit up, thank you for helping me
