A tessellation is a repetitive pattern of polygons that fit together without overlapping without gaps between them. For each tessellation, find the measure of each angle at the circled vertex. Then find the sum of the angles

i dont know i just need points

step-by-step explanation:

where are the choices?

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
