Answer 2

$\large\blue{\maltese{\purple{\bold{AnsweR}}}}$

➙ x = 20 ✔

$\large\blue{\maltese{\purple{\bold{Step\:by\:step\: explaination}}}}$

★ Given that ,

$\begin{cases}∠C = \text{2x + 10} \\∠B = \text{3x - 10 }\end{cases}$

★ We know that opposite sides of the parallelogram are always equal .

So , ∠C = ∠B

᠉According to the question :

➙ ${\boxed{\bf{2x+10=3x-10}}}$

➙ 10 + 10 = 3x - 2x

➙ x = 20

$\therefore$ The value of the 'x' is 20

★ Verifying ,

➙ 2 × 20 + 10 = 3 × 20 - 10

➙ 40 + 10 = 60 - 10

➙ 50 = 50

➙ LHS = RHS

Hence verified ✔
