Write the converse, inverse, and contrapositive for the conditional statement. And tell whether it is true or false. If a polygon is a trapezoid, then it is a quadrilateral.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
