Two parallel lines, m and n, are cut by a transversal, t, as shown in the figure below. If m<2= 2x+7 and m<7= 3x-13, what is the measure of <7? picture will be shown in the comments

m<2 nd m<6 are corresponding angles since m//n and t is transversal.
so
m<2=m<6
m<6=2x+7
m<6=m<7 (m<6 nd m<7 are vertically opposite angles)
so
m<6= 3x-13,
2x+7=3x-13
Does that help? @an12345

ok
OpenStudy (anonymous):
ugh i dont get the end of the 1st question
OpenStudy (anonymous):
so like i got 2x-3x= -13-7
OpenStudy (anonymous):
then i got -x = 20
OpenStudy (anonymous):
so is the answer 20? its one of the choices

2x-3x=-13-7
-x=-20
x=20
they have askd u to find m<7.
so
u have to find
3x-13. u knw the value of x. plug in it in 3x-13 nd find m<7
OpenStudy (anonymous):
ahh ok
OpenStudy (anonymous):
ok it will be 47 that's one of the choices thank u!!
