Answer:
The correct answer is "9√2 units".
Step-by-step explanation:
The given equations are:
⇒
...(equation 1)
⇒
...(equation 2)
According to the 2nd equation, we get
⇒ 
⇒ 
On substituting the value of "y" in the 1st equation, we get
⇒ 



On taking common, we get

On applying factorization, we get





or,


Now,
The points are:
(-7, 12) = (x₁, y₁)
(2, 3) = (x₂, y₂)
By using the distance formula, the length of chord will be:
= 
On substituting the values in the above formula, we get
= 
= 
= 
=
units
Answer:
Step-by-step explanation:
Answer:
-4 3/4
Step by step explanation:
point D is 4 numbers to the left of the 0, meaning it is a negative 4. Then there is also a 3/4 of space between the 4 and point D, meaning point D is -4 3/4 away from 0.
Because it is a 90° angle and the legs are congruent, the legs intersect with the hypotenuse at the same angle, so the other, unnamed angle at the bottom left is equal to x.
Now we can state that:
2x + 90 = 180
2x = 90
x = 45
