Answer:
82 cm
Step-by-step explanation:
In rectangles diagonals are equal and bisect each other
AO = BO
5x + 1 = 4x + 9
Subtract 1 from both sides
5x = 4x + 9 -1
5x = 4x + 8
Subtract 4x from both the sides
5x - 4x = 8
x = 8
AO = 5x + 1
= 5*8 +1
= 40 + 1
AO= 41 cm
Diagonal = 2*41 = 82 cm
Triangles a are similar because they have the same degrees
And Triangles d are similar because they are the same shape
Answer:
The property that I would use is that however many decimal points are in the equation is the number of decimal places in the answer
Step-by-step explanation:
Answer:
x = - 7
Step-by-step explanation:
( x + 139 ) and 132 are vertically opposite angles.
Vertically opposite angles are equal,
x + 139 = 132
x = 132 - 139
x = - 7
