Step 1
<u>Find the value of s</u>
we know that
In a Rhombus all sides are congruent
so


equate AB and CD

Combine like term


<u>The answer Part a) is</u>
the value of s is 
Step 2
<u>Find the value of side AB</u>

substitute the value of s

Remember that the sides are congruent

therefore
<u>the answer Part b) is</u>
The length of the side BC is 
First you can count multiples of 7 all the way up to 84. 7,14,21,28,35,42,49,56,63,70,77,and 84.
Or you can do 7 x 12 equals 84.
Second write down the long division way 84/7.
7 goes into 8 one time write 7 at the top then write one at the bottom bring down the 4 and make it 14
you know 7 x 2 = 14 so 12 x 7 equals 14.
Answer:
h = 5 cm
Step-by-step explanation:
Given that,
The volume of ice-cream in the cone is half the volume of the cone.
Volume of cone is given by :

r is radius of cone, r = 3 cm
h is height of cone, h = 6 cm
So,

Let
is the volume of icecream in the cone. So,

Let H be the depth of the icecream.
Two triangles formed by the cone and the icecream will be similiar. SO,

So, volume of icecream in the cone is :

or
h = 5 cm
So, the depth of the ice-cream is 5 cm.
Step-by-step explanation:
The fraction is 4/10 * 2/9 = 4/45.
