The sum of all interior angles in a polygon is
180(n-2), where n = sides, well, this is a QUADrilateral, so it has 4 sides, so the total is 360°.
now, let's find what angle C is first,

now, recall the "inscribed quadrilateral conjecture", where opposite angles are "supplementary angles", thus
A because 1-10 would be -9 and she was a meter above so positive but they descended 10 meters no negitve
Answer:
b = square root of 44 or approx. 6.6
