Slope of AD = (2k - 0)/(2j -b - 0) = 2k/(2j - b)
slope of BC = (2k - 0)/(2j - b) = 2k / (2j - b)
AD ║ BC (same slope)
Slope of AB = 0
Slope of DC = 0
AB║DC
Answer:
Step-by-step explanation:
20-pack of Dr. Pepper cost $5.50 . As per this deal
Cost of one pack = 5.5/20 = $ 0.275
a 6-pack cost $1.50.As per this deal
Cost of one pack = 1.50/6 = $ 0.25
A 6-pack cost $1.50 is the better deal.
32's 1/8 = 32/8 = 4
This is the simplest form
-7x + 6 = 27
-7x = 21 (Subtract 6 from both sides)
x = -3 (Divide -7 from both sides)
Answer: The correct option is (a), i.e., cos B= sin A.
Explanation:
It is given that the ∠B = ∠C and ∠D is a right angle.
Since two corresponding angles of both triangles are same, so by angel sum property three angles are also equal. Therefore by AAA rule both triangles are similar.
It is given that,


Using angle sum property angle C is written as,



By using quadrant concepts.

Therefore option A is correct.
