What are the missing lengths ???
lesantik [10]

Answer:

1. c = 13

2. a = 20

Step-by-step explanation:

1. 12² + 5² = x²

144 + 25 = x

144 + 25 = 169

√169 = 13

2. 29² - 21² = x²

841 - 441 = x

841 - 441 = 400

√400 = 20

\boxed{ \boxed{\huge{ \mathrm{  \underline{ Answer } ✓ }}}}

<u>Figure - 1</u> :

Let the missing side as " n "

\mathrm{ \triangle DEF    \sim   \triangle DRQ}

Therefore the sides will be proportional,

  • \dfrac{n}{9}  =  \dfrac{4}{12}

  • n =  \dfrac{1}{3}  \times 9

  • n = 3 \:  \: units

_____________________________

<u>Figure - 2</u> :

Let the missing side as " m "

The Triangles are similar, therefore their sides will be proportional.

  • \dfrac{m}{8}  =  \dfrac{9}{6}

  • m =  \dfrac{3}{2}  \times 8

  • m = 3 \times 4

  • m = 12 \:  \: units
