Answer:
x=7.5
Step-by-step explanation:
3(x+4.5)=36
Distribute
3x+13.5=36
36-13.5=22.5
3x=22.5
22.5/3=7.5
x=7.5
Answer:
question 4 ... x = -11
question 5.... x = -7
question 6... x = 12
question 7.... x = 10
Step-by-step explanation:
note : the total angle of a triangle is 180 degrees
hence solve this by creating an equation
x + 51 + 60 + 80 = 180
x = 180 - 80 -60-51
x = -11
note : the total angle of a triangle is 180 degrees
hence solve this by creating an equation
remember that a right angle is 90 degrees
45 + 52+x + 90 = 180
x = 180 - 90 -52 -45
x = -7
note : the total angle of a triangle is 180 degrees
hence you can solve this by creating an equation
53 + 39+ 4+7x = 180
now make x the subject of the equation
7x = 180 - 53 - 39 - 4
7x = 84
x = 84/7
note : the total angle of a triangle is 180 degrees
hence solve this by creating an equation
6x - 5 + 5x + 75 = 180
now make x the subject of the equation
6x +5x = 180 - 75 + 5
11x = 110
x = 110/11
Answer:
C = 25 Centimeters
Its very simple\
To find the values of x2 and y2 for point G(0,0) when you are given that G is the midpoint of points (x1, y1) and (x3, y3), you can use the midpoint formula:
Midpoint formula:
(x, y) = ((x1 + x3) / 2, (y1 + y3) / 2)
Given:
(x1, y1) = (2, 3)
G(0, 0)
Plug these values into the midpoint formula:
(0, 0) = ((2 + x3) / 2, (3 + y3) / 2)
Now, solve for x3 and y3:
For x3:
0 = (2 + x3) / 2
Multiply both sides by 2 to isolate x3:
0 = 2 + x3
Subtract 2 from both sides to find x3:
x3 = -2
For y3:
0 = (3 + y3) / 2
Multiply both sides by 2 to isolate y3:
0 = 3 + y3
Subtract 3 from both sides to find y3:
y3 = -3
So, the values are:
x3 = -2
y3 = -3
Therefore, the coordinates for point (x2, y2) are:
x2 = 3
y2 = -3
b. AB=CD
c. BAD=BCD
d. AC=BD
Answer:
(D)
Step-by-step explanation:
It is given that The diagonals of parallelogram ABCD intersect at point E.
then, using the properties of parallelogram, we get
(A) BD bisects AC
This is correct statement because the diagonals bisect each other in parallelogram.
(B) AB=CD
This is correct statement because the opposite sides of the parallelogram are equal.
(C) ∠BAD=∠BCD
This is correct because opposite angles of the parallelogram are equal.
(D) AC=BD
This is not necessarily true, because if the diagonals of parallelogram are equal, then it is a rectangle.
Hence, option D is correct option that is not necessarily true.
