A scale factor of 3 means that the new shape is three times the size of the original. To calculate the Scale Factor, we use the following: You can get the 'big' and 'small' from the corresponding sides on the figures. So just get your # and multiply it by 3
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
Answer:
100,80
Step-by-step explanation:
The opposite angle theorem states that, : "When two lines cross four angles are created and the opposite angles are equal."
y°=80°
Now, check that , x° and y° are in one straight line. A straight line has angle of 180°. So x° and y° should sum up to 180°
x° + y° = 180°
x° + 80° = 180°
x° = 100°
<h2>

To find, the value of x = ?
We know that,
Consecutive angles are supplementary
The diagonals bisect the angles.

Divided by 2 both sides, we get
⇒ 
⇒ 
⇒ 
⇒ 4x = 
⇒ 
⇒ 
∴ The value of x =
Thus, the required "option B)
" is correct.
Answer:
No
Step-by-step explanation:
6^2+4^2=52
7^2=49
49 is not equal to 52, so no it is not a right triangle
