Y=x so y=1*x and for x-value, the y-value gets multiplied by 1 since "y=1*x" therefore it is a multiplicative relationship.
First, you need to multiply 2*21cm, which gives us 42 cm.
Then we multiply it by π, or 22/7 in this case, and 22/7*42cm gives us 132 cm.
So the answer is: 132cm.

We know that the three angles of a triangle always add up to 180.
Therefore, we have the equation:
55+20+x=180.
Solving for x, we get x=105.
The GCF of 8x and 40 is 8
40 | 2

40 = 2³ * 5
8 = 2³
We take only common factors with lowest exponent.
So 2³ = 8
