Answer;

-13 cm

Explanation;

The perimeter of quadrilateral JKLM is 90 centimeters.

JK = n + 7

KL = n

JM = 3n + 4

LM =  2n-12

Therefore; since the perimeter is the sum of the lengths of all the sides;

= n + n+7 + 3n + 4 + 2n -12 = 90

= 7n - 1 = 90

7n = 91

n = 91/7

n =  13 cm

Hence; KL = 13 cm

The figure is not given for this question. It would be more helpful if you understand what is a perimeter. The sum of the side lengths of a shape is called the perimeter. A quadrilateral is a polygon with four edges which means four side. Side KL should be one of them. The length of this side should be 90 minus the 3 side lengths. Hope this could help.

Step-by-step explanation:

Since ,

Money lended =$400

Intetest =27.74%

Therefore,

Intetrst=p×r×t/100,if interested monthly

=400×27.74×1/100(interested monthly)

=4×27.74

=$110.96

Interest=p×r×t/100×1/12,if interested anually

=400×27.74×1/100/12

=110.96/12

=$9.24 or it will be $110.96 if it is interested anuaaly..

5. What is the<br> complement of the<br> supplement of a 110° <br> angle?
Slav-nsk [51]
<h2>Answer:   20°</h2>

<h3>Step-by-step explanation:</h3>

Supplementary angles sum up to 180 °

Complementary angles sum up to 90°.

The supplement of 110° = 180° - 110° = 70°

The complement of 70° = 90° - 70° = 20°

<u>Simplier version:</u>

The complement of the supplement of 110° = (90° - (180° - 110°))

                                                                         = 20°
