Answer:
m<C = 119°
Step-by-step explanation:
Create an equation to find the value of x.
(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)
Solve for x
9x - 26 = 2x - 12 + 4x + 43
Add like terms
9x - 26 = 6x + 31
9x - 6x = 26 + 31
3x = 57
Divide both sides by 3
x = 19
✔️m<C = 4x + 43
Plug in the value of x
m<C = 4(19) + 43
m<C = 76 + 43
m<C = 119°
Answer:
Total cost of polishing the floor is Rs/500.
Step-by-step explanation:
The floor consists of 2000 tiles which have the shape of a rhombus.
Area of rhombus =
Where: and are the diagonals.
Given that:
= 40 cm = 0.4 m
= 25 cm = 0.25 m
Then,
Area of each tile =
=
= 0.05
Area of each tile is 0.05 .
Since there are 2000 tiles on the floor of the building, then;
Total area covered by the tiles = 0.05 x 2000
= 100
The total cost of polishing the floor = 100 x Rs/5
= Rs/500

Answer:
The area of the rectangular field is<u> 2831.25</u> sq. yards.
The perimeter of the rectangular field is<u> 153.1</u> yards
Step-by-step explanation:
Here, the length of the field = 62. 5 yards
The width of the field = 45.3 yards
PERIMETER OF A RECTANGLE = 2 (LENGTH + WIDTH)
⇒ The perimeter of the yard = 2 ( 62.5 + 45.3)
= 2 x (107.8) = 153.1 yards
or the perimeter of the rectangular field is 153.1 yards
Area of a Rectangle = (LENGTH x WIDTH)
⇒ The area of the yard = ( 62.5 x 45.3)
= 2831.25 sq. yards
or the area of the rectangular field is 2831.25 sq. yards.
Answer: (-1,3)
(0,1)
(1,-1)
(2,-3)
Step-by-step explanation: For example, you put -1 as x in the equation, and then solve, your answer would be the y, and the number you inputted would be the x.
