Explanation & Answer
8) Angle DMV = 110 degree
9) Angle AME = 180 degree
10) Angle AMC = 90 degree
11) The end points are C(2, 9) and D(-2, -9)
Now The midpoints can be find using midpoint formula, then
midpoint = [ (2 + (-2))/2 , (9 + (-9))/2 ]
midpoint = [ (2 - 2)/2 , (9 - 9)/2 ]
midpoint = [ (0)/2 , (0)/2 ]
midpoint = [ 0 , 0 ]
Length of the segment is
length = √(- 2 - 2)^2 + (- 9 - 9)^2
length = √(- 4)^2 + (- 18)^2
length = √16 + 324
length = √340
length = 18.44
12) The end points are E(4, -8) and F(-6, 6)
Now The midpoints can be find using midpoint formula, then
midpoint = [ (4 + (-6))/2 , (-8 + 6)/2 ]
midpoint = [ (-2)/2 , (-2)/2 ]
midpoint = [ -1 , -1 ]
Length of the segment is
length = √(- 6 - 4)^2 + ( 6 + 8)^2
length = √(-10)^2 + (14)^2
length = √100 + 196
length = √296
length = 17.21
13) angle TEA = 70 degree
angle TEF = ?
angle FEA = ?
As EF is bisecting the angle then
angle TEF = 35 degree
angle FEA = 35 degree
