Answer:
A) 68
Step-by-step explanation:
Use the <em>Exterior Angle Theorem</em>.
The Exterior Angle theorem states that the exterior angle's measurement will be equal that of the two opposite interior angles.
Set the equation. Note that you are given the exterior angle and one interior angle:
58 + x = 126
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 58 from both sides of the equation:
x + 58 (-58) = 126 (-58)
x = 126 - 58
x = 68
A) 68 is your answer.

Answer:
should be 63
Step-by-step explanation:
A square is a figure with four equal sides and four right angles.In a square the diagonals bisect at right angles .
In the above given options option A is the right answer.
If the diagonals of any parallelogram are perpendicular then the figure is not necessarily a square.
Diagonals are perpendicular in a rhombus too.
A square and Rhombus both have diagonals that are perpendicular.
So it is not a necessary condition for a parallelogram to be a square .
The other options are right .
So option B is the right option that if diagonals are perpendicular is not sufficient to prove the figure to be a square.
Answer:
C. 3.2
Step-by-step explanation:
Heights of dogs: 10, 22, 15, 12, 16
✔️Find the mean of the data set = 
✔️Find |data value - mean|:
|10 - 15| = 5
|22 - 15| = 7
|15 - 15| = 0
|12 - 15| = 3
|16 - 15| = 1
✔️Find the sum of |data value - mean| and divide by 10:

✅M.A.D = 3.2
