Question

16. In a parallelogram WXYZ,∠W=(2x+20)°and ∠Y=(3x-30)°,find the value of x.

Answer 1

$\text{From the properties of parallelogram, we know two opposite angles are equal}\\</p><p></p><p>\implies \angle W = \angle Y \\</p><p>\implies 2x + 20 = 3x - 30 \\</p><p>\implies x = 30 + 20\\</p><p>\implies x = 50°</p><p>$
