This is false... you can get an easy example: (-2) + (10) = 10 - 2 = 8
Answer:
Therefore 'x' is equal to 65.4°
Step-by-step explanation:
In Right Angle Triangle ABC
∠ B = 90°
AC = Hypotenuse = 12
CB = Adjacent Side = 5
To Find:
∠ C = x
Solution:
In Right Angle Triangle ABC Cosine Identity we have

Substituting the values we get


Therefore 'x' is equal to 65.4°
Answer:
E(3.75,-2.5)
G(-0.75,-3)
Step-by-step explanation:
Point E is the midpoint of the segment AB, then it has coordinates

Point F is the midpoint of the segment EB, then it has coordinates

Let S be the midpoint of segment CB, then it has coordinates

Point G is the midpoint of segment CS, then its coordinates are
