What do all of these polygons have in common? There are four polygons labeled A, B, C and D. Each polygon has one pair of parallel sides. A. Each appears to have exactly two pairs of parallel sides. B. Each appears to have exactly one pair of parallel sides. C. Each appears to be a quadrilateral. D. Each appears to be a trapezoid.

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure

b is the correct answer

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
