Question

16. Two opposite angles of a parallelogram are (4x–20)0 and (40–x)0. Find the value of x. ​

Answer 1

Answer:

x=53.33 or 160/3

Step-by-step explanation:

adding of opposite angles of a parallelogram =180°

so here (4x-20)+(40-x)=180°

solve this u'll get x value

Answer 2

Answer:

$\huge\underline\orange{Question}$

Two opposite angles of a parallelogram are (4x–20)° and (40–x)°. Find the value of x.

$\large{\bold{\underline{\underline{\pink{\bf{req}\green{uir}\red{ed}\:\orange{ans}\blue{wer}}}}}}$

$\huge{\underline{\underline{\tt{\blueſ.Value\ of\ x}}}}$

$\fbox{\LARGE{\underline{\underline{\pink{\bf{Solution}}}}}}$

Since opposite angles of a parallelogram are equal. Therefore,

4x−20=40-x

4x+x=40+20

5x=60

x=$60 \div 5$

x=12
