The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)

xz_007 [3.2K]

Answer:

The measure of the sides is 20 cm.

Step-by-step explanation:

Opposite side of a parallelogram:

Opposite sides of a parallelogram are congruent, that is, they have the same measure.

Measures (2x+10) cm and (x+15) cm:

This means that:

$2x + 10 = x + 15$

$2x - x = 15 - 10$

$x = 5$

2x + 10 = 2*5 + 10 = 10 + 10 = 20

The measure of the sides is 20 cm.

Find the length of BC.<br><br><br><br>Explain how you got it, please!<br>Thanks!

Vinvika [58]

Answer:

BC = 30.73

Here,

$\sf \frac{AB}{BQ} = \frac{CD}{DQ}$

so first solve for QD

$\sf \hookrightarrow \frac{32}{15} = \frac{19.2}{DQ}$

$\sf \hookrightarrow 32(DQ)} =19.2(15)$

$\sf \hookrightarrow 32(DQ)} =288$

$\sf \hookrightarrow DQ =9$

Hence, QD = 9

Now! <u>using Pythagoras theorem,</u>

CD² + BD² = BC²

19.2² + (9+15)² = BC²

BC = √368.64+576

BC = 30.73499634

BC = 30.73 ( rounded to nearest hundredth )
