Question

angles of quadrilateral are 4x°,5(x+2)°, (7x-20°) and 6(x+3)°. find a. the value of x b. each ane of the quadrilateral

Answer 1

$4x + 5(x + 2) + 7x - 20 + 6(x + 3) = 360 \\ 4x + 5x + 10 + 7x - 20 + 6x + 18 = 360 \\ 22x + 8 = 360 \\ 22x = 352 \\ x = 352 \div 22 \\ x = 16 \\ 4x = 64 \\ 5(x + 2) = 90 \\ 7x - 20 = 92 \\ 6(x + 3) = 114$
