116+y=180(sum of angles in a straight line)
y=180-116
y=64
x+y+125+72=540(sum of angles in a quadrant)
x+64+125+72=540
x+125+136=540
x+261=540
x=540-261
x=79
Answer:
B
Step-by-step explanation:
The midpoint of EF is M. The length of EM is 5
Given :
The endpoints of EF are E(2, 3) and F(8, 11).
M is the midpoint of EF
Lets find out the midpoint M using midpoint formula

Substitute the values inside the formula

Midpoint M is (4,7)
Now to find out length of EM, we use distance formula

So, length of EM= 5
