the measures of two adjacent sides of a parallelogram are in the ratio 17 : 7. If the second side measures 3.5 cm, find the peri

Setler [38]

Answer:

24 cm

Step-by-step explanation:

Given that there is a parallelogram and adjacent sides are in the ratio

17:7

The second side =3.5cm

So we have x:3.5 = 17:7 where x is the unknown first side

Solve using ratio property to get

3.5(17) = 7x

Or x = 8.5 cm

Perimeter of parallelogram = sum of all sides

= 2(sum of one pair of adjacent sides)

=2(8.5+3.5)

=2(12)

=24 cm

Question 3

Scilla [17]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the vertices of the triangles is missing.

However, the following formula can be used to calculate distance;

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

Take for instance:

$A = (1,8)$

$A' = (7,8)$

The distance between both is:

$d = \sqrt{(1- 7)^2 + (8- 8)^2}$

$d = \sqrt{(-6)^2 + 0^2}$

$d = \sqrt{36 + 0}$

$d = \sqrt{36}$

Take square root

$d = 6$

<em>Apply the above steps to the complete question</em>
