What is the value of s and the length of side BC if ABCD is a rhombus?

Natali5045456 [20]

Step 1

<u>Find the value of s</u>

we know that

In a Rhombus all sides are congruent

so

$AB=BC=CD=DA$

$AB=9s+29\\CD=10s-16$

equate AB and CD

$9s+29=10s-16\\$

Combine like term

$10s-9s=29+16\\$

$s=45\ units$

<u>The answer Part a) is</u>

the value of s is $45\ units$

Step 2

<u>Find the value of side AB</u>

$AB=9s+29$

substitute the value of s

$AB=9*45+29=434\ units$

Remember that the sides are congruent

$AB=BC=CD=DA$

therefore

<u>the answer Part b) is</u>

The length of the side BC is $434\ units$
