@518nad

OpenStudy (thatcluelessgirl):

great your here I need your help @mathmale

OpenStudy (mathmale):

I'd suggest you get started now if you're in a hurry to finish this problem. I'm sure you know at least some of the material you need to answer this question.

OpenStudy (mathmale):

How many degrees in <AEB?

OpenStudy (thatcluelessgirl):

iv got the first three done

OpenStudy (thatcluelessgirl):

ABE is27

OpenStudy (mathmale):

Important that you let people know that up front, so time's not wasted re-inventing the wheel. What's difficult about #4?

OpenStudy (thatcluelessgirl):

let me check

OpenStudy (mathmale):

Actually, it's <AEB you mentioned, and that's 28 degrees.

OpenStudy (thatcluelessgirl):

ok what does 3m mean

OpenStudy (mathmale):

What is "measure of angle AEB?" It's not 27 degrees.

OpenStudy (mathmale):

"3m<BEC" means "three times the measure of angle BEC."

OpenStudy (thatcluelessgirl):

28 sorry

OpenStudy (thatcluelessgirl):

oh ok I get 4 now

OpenStudy (mathmale):

Glad you're off to a good start. I will leave you for a while and encourage you to finish the rest of this assignment. If you have problems with other questions, just tag me. I will be off OpenStudy for a while.

OpenStudy (thatcluelessgirl):

@tHe_FiZiCx99 help

jhonyy9 (jhonyy9):

hello girl are you here ?

OpenStudy (royalranger):

What question are you on?

OpenStudy (thatcluelessgirl):

@royalranger I'm on 5

OpenStudy (royalranger):

Alright, so what is half of angle BED?

OpenStudy (thatcluelessgirl):

is 1/2 of bed going to be 32.5

OpenStudy (royalranger):

Not possible. Angle BED is 47 + 65. So what is half of that?

OpenStudy (thatcluelessgirl):

that's 112

OpenStudy (royalranger):

what is half of 112?

OpenStudy (thatcluelessgirl):

56 is half

OpenStudy (thatcluelessgirl):

4x28=112+56=168

OpenStudy (royalranger):

yep

OpenStudy (thatcluelessgirl):

ok these next ones are ones I need major help on

OpenStudy (thatcluelessgirl):

@royalranger

OpenStudy (royalranger):

Do you know what supplementary means?

OpenStudy (thatcluelessgirl):

arnt they =90

OpenStudy (royalranger):

Complementary is 90. Supplementary is 180.

OpenStudy (thatcluelessgirl):

oh I had it backwords so how do I solve six

OpenStudy (royalranger):

Since we know that they equal to 180 degrees. We can add the two angles and set them equal to 180. Then solve for x.

OpenStudy (thatcluelessgirl):

so what do I add

OpenStudy (thatcluelessgirl):

8x+4=180 180-4=176/8=22 am I right so far @royalranger I'm not bothering you am i

OpenStudy (royalranger):

Remember, both of the angles together is 180. So we need to add (8x +4) + 14x = 180

OpenStudy (thatcluelessgirl):

I'm lost now what do I do @royalranger

OpenStudy (royalranger):

you need to solve for x

OpenStudy (thatcluelessgirl):

so do I add the x's

OpenStudy (royalranger):

yes

OpenStudy (thatcluelessgirl):

them x is 22 what do I do with the 4

OpenStudy (royalranger):

\[8x + 4 + 14x = 180\] \[22x + 4 =180\] \[22x = 176\] \[x = 8\]

OpenStudy (thatcluelessgirl):

oh is that it

OpenStudy (thatcluelessgirl):

is 7 x=15 @royalranger

OpenStudy (royalranger):

Yup
