2500

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
