We will calculate it like this, We will make a right angle triangle by adding one new point called O for example, and O is located right under the point C, and on the right side of point D, so the coordinated for this point are O (8, -2). From there, length CD is calculated using the Pythagorean theorem, because we know that the CO = 4 and DO = 4, so:
CD^2 = CO^2 + DO^2
CD^2 = 4^2 + 4^2
DC^2 = 16 + 16
DC^2 = 32
DC = square root of 32 = square root of 16 * square root of 2
DC = 4 * square root of 2
The correct answer is B. 4*square root of 2.
360 degrees.
Hope this helps :)

To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, that's ur answer.
Answer:
original price= $150, sale price= $105
Step-by-step explanation:
since it is on sale for 70% of original price, there is 30% off discount.
$45 is 30% of original price (original price is 100%)
1% of original price
= $45 ÷ 30
= $1.50
original price
= $1.50 × 100
=$150
sale price (70% of original price)
= $1.50 × 70
= $105
