Rewrite equations
Y/7=15/3 Y/7=5 Now multiply out 7 Y=5×7 Y=35 To check
35/7=15/3
5=5 it checks
Answer:
a
Step-by-step explanation:
the length is what will tell you
Answer:
E. is 103 degree.
It's a vertical angle.
F. is 77 degree
the e and f makes a 180 degree. 180-103(aka e) = 77 degree
D. is 90 degree. it's perpendicular.
Answer:
They are parallel
Step-by-step explanation:
They both start with y=2/3x so you know the slope is the same. The +4 and -1 are just the intercepts
