Answer:

1. x=24

2. b) 15ft, 39ft, 36 ft.

Step-by-step explanation:

Working out for 1)

${25}^{2} - {7}^{2} = 576 \: and \: \sqrt{576} = \: 24$

Working out for 2)

${15}^{2} + {36}^{2} = 1521 \: and \: \sqrt{1521} = \: 39$

49+x^2=625

x^2=576

x=24

2. 15^2+36^2=39^2

<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

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