When to lines intersect they create four angles. Each angle is opposite to another and form a pair of what are called opposite angles. Angles a and c are opposite angles. Opposite angles are equal.
Answer:
Length = 21.3333333333; Width: 12.6666666667
Step-by-step explanation:
Perimeter = 68
Perimeter of a rectangle:
2 (L +W)
Length (L) = 2W - 4
Width = W
2 ( 2W -4 +W) = 68
=> 2 (3W - 4) = 68
=> 6w -8 = 68
=> 6w = 76
=> w = 12.6666666667
Length = (12.6666666667 X 2) - 4
=> 21.3333333333
120/10 = 12*6=72
120-72=48 answer = 48
Three lines creating six angles
3 angles on top, 3 angles below
Since the top left angle is a right angle
It means the line that divides the top angles from the angles below is bisected by a perpendicular line.
This means the sum of the angles of the top left = 90°
Therefore, x + 61° = 90°
x = 90° – 61°
x = 29°
