<h3><u>Answer:</u></h3>

\boxed{\pink{\sf\leadsto Value \ of \ x \ is \ 24^{\circ}}}

<h3><u>Step-by-step explanation:</u></h3>

In the given parallelogram we can see that , <B is 5x° and <C is equal to 2x + 12°.

And these two are co - interior angles . And sum of co - interior angles is 180°.

Hence , here

\tt:\implies \angle DCB + \angle ABC = 180^{\circ} \\\\\tt:\implies (2x + 12)^{\circ} + 5x^{\circ}=180^{\circ} \\\\\tt:\implies 7x = (180 - 12 )^{\circ} \\\\\tt:\implies 7x = 168^{\circ} \\\\\tt:\implies x =\dfrac{168^{\circ}}{7} \\\\\underline{\boxed{\red{\tt\longmapsto x = 24^{\circ}}}}

<h3><u>Hence the value of x is 24°</u><u>.</u></h3>

Answer is choice B

The ratio of the sides (first to the second) is 11/9 since we divide 22/18 and reduce that fraction

Once we know the scale factor is 11/9, we square it to get (11/9)^2 = 121/81 which is the ratio of the first area to the second area

vazorg [7]
Hello! A way we could solve this equation is to divide 714 by three and then multiply the quotient by 2 to get the number of men that attended. 714/3 is 238. There were 238 women that attended the concert. 238 * 2 is 476. 476 + 238 = 714. There. There were 476 men that attended the concert.
