can somone help me

OpenStudy (anonymous):

With?

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

OpenStudy (anonymous):

Solving for all the letters or just some?

OpenStudy (anonymous):

i think its d

OpenStudy (anonymous):

i dont understand it

OpenStudy (anonymous):

Ok do you know the angle of a straight line?

OpenStudy (anonymous):

180 and its e and f

OpenStudy (anonymous):

Yeap so we know then if the angle by E is 60 degrees then E would be 180 degrees - 60 degrees which give us 120 degrees for E

OpenStudy (anonymous):

how did you get 120

OpenStudy (anonymous):

Ok so a line is 180 Degrees we know 60 degrees of that is the angle next to E correct?

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

ohhhh

OpenStudy (anonymous):

180-60=120

OpenStudy (anonymous):

so know we know the angle of E we know the angle G is equal to that angle right?

OpenStudy (anonymous):

and angle F is equal to the 60 degree angle

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

you add them and get 120

OpenStudy (anonymous):

add what and get 120 hold on ill make a diagram

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

are you there?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Does this make sense?

OpenStudy (anonymous):

im reading it

OpenStudy (anonymous):

Start Read Blue Green Orange Reading in order

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

if a is 60 degrees then d is also 60

OpenStudy (anonymous):

right?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

then do we have to subtract 105-60?

OpenStudy (anonymous):

Since there are 3 angles all three of those have to equal 180, so you have to figure out two of the angles before you can find the third. No so we know angle A is 60 degrees and we have the angle of 45 degrees and we know D + 45 + A(60) has to equal 180 So we add what we have 45 + A(60) which is 105 right Now we need it to equal 180 the whole thing so if we subtract the sum of the two angles we have (105) from the total degree of a line we will get out answer for the last angle

OpenStudy (anonymous):

so its 75

OpenStudy (anonymous):

Correct but you do fully understand why?

OpenStudy (anonymous):

i think so but would it also be done correctly if you were to subtract 180-45-60?

OpenStudy (anonymous):

Yes do you know where you are getting your 180 from and why you must subract those angle from it?

OpenStudy (anonymous):

because there are supposed to be 3 so the 3 is equal to 180?

OpenStudy (anonymous):

Correct because the 3 form a line and a line equal 180 Degress

OpenStudy (anonymous):

THANK YOU SO MUCH!!!!! this is my first time using this website

OpenStudy (anonymous):

no problem glad I could help
