\[\frac{4}{10}=\frac{10}{AB}\]cross ,time
4*AB=10*10
4AB=100
AB=100/4
AB=25
OpenStudy (anonymous):
thank you so much :)
OpenStudy (anonymous):
u r welc

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):

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

thats the question

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

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

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
