Step-by-step explanation:
x = 145°
we don't even need the upper parallel line with the 35° angle.
it is simply based on the fact that the angles on both sides of 2 intersecting lines have to be the same (just left-right mirrored).
Answer:
a) 7 tiles
b)4 1/3 tiles*
Step-by-step explanation:
*you would need 5 tiles if the answer isn't supposed to be a fraction. 4 1/3 is the exact amount but if they are asking for whole tiles you need to put 5. since they didn't actually specifiy that i don't think you have to worry about it. i would go with 4 1/3 tiles
Answer:
Y = 6
X = 24
Step-by-step explanation:
2x -5y = 16
(x -2y =5)*2
_______________
2x -5y = 16
2x - 4y = 10
_______________
(2x -5y = 16) - (2x - 4y = 10)
_______________
0x -y = 6
_______________
y =6
_______________
Replacing in equation 1:
2x - 5(6) = 16
so, 2x = 16 + 30
2x = 48
x = 24
The perimeter of a polygon or any shape is just the sum of all of its sides. If you are asked to find the perimeter of a polygon, you would simply just add all the sides together. For example, if a square has 4 sides with the length 2m, the perimeter of that square would be 2m + 2m + 2m + 2m = 8m. Perimeter just means add all the sides.
