Question

two adjacement angles of a parallelogram are (3x-4) and (3x+10). find the angles of the parallelogram

Answer 1

$(3x - 4) + (3x + 10) = 180$
(because sum of adjacent angles of parallelogram is 180)

=>
$3x - 4 + 3x + 10 = 180$
$9x + 6 = 180$
$9x = 174$
$x = 174 \div 9$
$x = 19.33$

Hope this helps!
