When tiles are tessellated in a plane, what angle measure sum is required of the tiles surrounding a single point?

We know from basic geometry that the sum of angles about a point is always . Thus, in our case too this will remain the same and hence the angle will remain .

Therefore, when tiles are tessellated in a plane, the angle measure sum that is required of the tiles surrounding a single point is always .

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
