Answer:
Step-by-step explanation:
11 no
46+4x=90 degree(being perpendicular)
4x=90-46
x=44/4
x=11
12 no
They are complementary angles
6 no
angle B+27=180 degree(being straight line)
angle B=180-27
angle B=153
10 no
angle 38 +angle DFE=180 degree(being supplementary)
angle DFE=180-38
angle DFE=142 degree
5 no
They are vertically opposite angles.
7 no
angle AGF and angle CGD (because they have common arm and vertex)
Given that <span>C = { X | X + 6 = 10}
This can be interpreted grammatically as "C is a set X such that X is the solution to X + 6 = 10".
Given that X + 6 = 10
X = 10 - 6 = 4
Therefore, the solution is
C = {4}
