Refer to the figure below to find the measure. PlEASE help Given: If CR = 4, RA = 6, and RS = 10, find AB.

OpenStudy (anonymous):

OpenStudy (anonymous):

\[\frac{4}{10}=\frac{10}{AB}\]cross ,time 4*AB=10*10 4AB=100 AB=100/4 AB=25

OpenStudy (anonymous):

thank you so much :)

OpenStudy (anonymous):

u r welc If I deserve medal then give me one

OpenStudy (anonymous):

i did can you help me with another one ill give another medal :)

OpenStudy (anonymous):

Refer to the figure below to find the measure. Given: 1 = 2 If AC:BC = 3:5 and AB = 12, find AD: and DB:

OpenStudy (anonymous):

I will try

OpenStudy (anonymous):

did u get it?

OpenStudy (anonymous):

give me time ,u have another post come back

OpenStudy (anonymous):

another post? did u get the pic?

OpenStudy (anonymous):

yes, i mean u have another question chek

OpenStudy (anonymous):

oh yes i do do u want me to post it?

OpenStudy (anonymous):

yes

In the figure below, the segment is parallel to one side of the triangle. Find the values of x and y . x = y =

OpenStudy (anonymous):

OpenStudy (anonymous):

\[\frac{12}{10}=\frac{12+x}{10+15}\]cross ant time can u solve

OpenStudy (anonymous):

12x 15 = 180

OpenStudy (anonymous):

and 10 x

OpenStudy (anonymous):

find y\[\frac{10+15}{20}=\frac{10}{y}\]

OpenStudy (anonymous):

waoit whats x?

OpenStudy (anonymous):

the frist eqution I did send u solve fid x, u want me do it

OpenStudy (anonymous):

please?

OpenStudy (anonymous):

10x=12*15 x=180/10 x=18

OpenStudy (anonymous):

and y?

OpenStudy (anonymous):

\[\frac{10}{y}=\frac{25}{20}\] 20*10=25y y=200/25 y=4

OpenStudy (anonymous):

the triangle need moretime I think I can do it, u have another?

OpenStudy (anonymous):

yeah i do btw thanks for your help :)

OpenStudy (anonymous):

tha for medal, I still work on tri angle

OpenStudy (anonymous):

okay the next one is

OpenStudy (anonymous):

In the figure below, the segment is parallel to one side of the triangle. Find the value of x . x =

OpenStudy (anonymous):

OpenStudy (anonymous):

thats the question

OpenStudy (anonymous):

16x=12*(x+6) 16x=12x+72 16x-12x=72 4x=72 x=72/4 x=18

OpenStudy (anonymous):

im sorry i have u the wrong picture

OpenStudy (anonymous):

here it is

OpenStudy (anonymous):

22x=16*(x+7) 22x=16x+112 22x-16x=112 6x=112 x=112/6 x=18.7

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

no

OpenStudy (anonymous):

no thats not right :/

OpenStudy (anonymous):

yes let do again

OpenStudy (anonymous):

do u have the question i gave u?

OpenStudy (anonymous):

i thin o right

OpenStudy (anonymous):

i guess we could do another one

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

In the figure below, the segment is parallel to one side of the triangle. Find the values of x and y . x = y =

OpenStudy (anonymous):

30*10=15*x 300/15=x 20=x

OpenStudy (anonymous):

2+10=30 10y=12*30 y=360/10 y=36

OpenStudy (anonymous):

?

OpenStudy (anonymous):

hm one second

OpenStudy (anonymous):

correct thank you :)

OpenStudy (anonymous):

ur w v

OpenStudy (anonymous):

last one :) In the figure below, the segment is parallel to one side of the triangle. Find the values of x and y . x = y =

OpenStudy (anonymous):

12x=4*9 x= 36/12 x=3

OpenStudy (anonymous):

12*4=12y 48=12y y=48/12 y=4

OpenStudy (anonymous):

r u there?

OpenStudy (anonymous):

yes thank youi :)

OpenStudy (anonymous):

I have a answer for tri angle ,u have a key?

OpenStudy (anonymous):

\[\frac{3}{5}=\frac{AD}{12}\] 12*3=5AD 36 =5AD 36/5=AD 7.2 = AD 12-7.2=DB

OpenStudy (anonymous):

u have a key to check?

OpenStudy (anonymous):

thats correct

OpenStudy (anonymous):

good ,geometry take time to think, because when u go to school ,teacher don't teach ,students they always let student think
