First, we need to find the area of both the tile and cardboard, so we can calculate how much tile will fit in the cardboard
Answer:
868 (third option)
Step-by-step explanation:
we know that the area of original is
.
the new parallelogram will has area 
Answer:
x = 25°
Step-by-step explanation:
Applying,
Sum of the angle in the triangle = 180°
From the diagram,
First angle of the triangle = 55° (vertically opposite angles are equal)
Second angle of the traingle = 180-80 = 100° (sum of the angle in a straight line)
Third angle of the triangle = x
Therefore,
x+55+100 = 180
x+155 = 180
x = 180-155
x = 25°
