a. –7
b. –2
c. 1
d. 3
Answer:
B
Step-by-step explanation:
Start by using the distance formula to find the raidus
The two points are (-2,1) and (-4,1)
√((-4+2)²+(1-1)²)= 2
The radius is two and we have our center which means we can write
(x+2)²+(y-1)²=4
now it's just a matter of expanding everyhting
x²+4x+4+y²-2y-3=0
x²+y²+4x-2y+1=0
This is equal to B
If m∠ABC = 72°, what is m∠DAB?
Value of ∠DAB is 108°
Given that;
∠ABC = 72°
Find:
Value of ∠DAB
Computation:
We know that Line AD is parallel to line CB
So,
∠ABC + ∠DAB = 180°
72° + ∠DAB = 180°
∠DAB = 108°
Find out more information about 'Parallel line'
Answer: m∠DAB=72
Step-by-step explanation:
Since we have given that
∠ABC = 72°
Since the lines AD and BC are parallel to each other,
As we know that when the two parallel lines cut by a transversal then the corresponding angles will be formed.
And the corresponding angles will be equal.
So, m∠ABC =m∠DAB=72°
Hence, m∠DAB=72°

Answer:
20 people
Step-by-step explanation:
22 pancakes = 8 people
55 pancakes = x people
=> Cross-multiply
=> 22 * x = 55 * 8
=> 22x = 440
=> 22x/22 = 440/22
=> x = 20
So, 55 pancakes can feed 20 people.
