Question

In a quadrilateral ABCD, A = ( 2x + 4)0, B = (2x - 13)0, C = (3x + 11)0 and D = (4x - 5)0. Find the measures of the angles.

Answer 1

sum of angles in a quadrilateral =180,therefore 2x+4+2x-13+3x+11+4x-5=11x-3
x=3/11
therefore,
$2 \times 3 \div 5 + 4 = 1.2 + 4 = 5.2$
$2 \times 3 \div 5 - 13 = .... > > >$
