Answer: 3 and 5 are supplementary angles, and 1 and 4 are vertical angles.
Population, because the more people there are in a town, the more mailboxes and traffic lights there will be. There will have to be more in order to supply the population.
Answer:
The value of v with given slop and points is - 6
Step-by-step explanation:
Given as :
Let x and y be the points of a line
So, x = ( - 3 , - 10 ) And y = ( - 4 , v )
The given slop of line XY is - 4
Now, from slop equation :
Slop = 
Or, - 4 = 
Or, - 4 = 
Or, v + 10 = ( -4 ) × (- 1 )
Or, v + 10 = 4
∴ v = 4 - 10 = - 6
Hence The value of v with given slop and points is - 6 Answer
We are to solve the total area of the pyramid and this can be done through area addition. We first determine the area of the base using the Heron's formula.
A = √(s)(s - a)(s - b)(s - c)
where s is the semi-perimeter
s = (a + b + c) / 2
Substituting for the base,
s = (12 + 12 + 12)/ 2 = 18
A = (√(18)(18 - 12)(18 - 12)(18 - 12) = 62.35
Then, we note that the faces are just the same, so one of these will have an area of,
s = (10 + 10 + 12) / 2 = 16
A = √(16)(16 - 12)(16 - 10)(16 - 10) = 48
Multiplying this by 3 (because there are 3 faces with these dimensions, we get 144. Finally, adding the area of the base,
total area = 144 + 62.35 = 206.35
Answer:
Supplementary Angles
Adjacent Angles
Step-by-step explanation:
Angles 1 and 2 share a vertex and form a straight line. These angles are called supplementary angles. They add to 180 degrees and form a straight line. They are adjacent as well because they share a vertex and side.
