Question

If two opposite angle of a parallelogram are 63-3x and 4x-7.find all the angle of the parallelogram

Answer 1

we know that opposite angles of parallelogram are equal means
$63 - 3x = 4x - 7$
$63 + 7 = 4x + 3x$
$70 = 7x$
$x = 10$
means angle 1 =63-3x=63-30=33
angle 2 =33
angle 3=180-33=147
angle 4=147
