Given: ABCD is a parallelogram.Prove: ∠A and ∠D are supplementary.

Parallelogram A B C D is shown.

By the definition of a parallelogram, AB∥DC. AD is a transversal between these sides, so ∠A and ∠D are
angles. Because AB and DC are
, the same-side interior angles must be
by the same-side interior angles theorem. Therefore, ∠A and ∠D are supplementary.

Kat's dog runs around the perimeter Of a rectangular field. The diagonal Of the field is 25 yards in length and the field has a length Of 20 yards. HOW many total yards did Kat's dog run?

Answers

You figure it out lol

the area of the rectangle is 85 cm. express the perimeter of the rectangle is function of the width x.

Answers

the \ width : \ x \n the \ length : \ y \n The area : \ A=85 \n \nA=xy \n \n85=xy\n \ny= (85)/(x)
f(x)=85-2(y)  I think it is so .

how many elements must a set have if the number of proper subsets of the set 1/2 of the total number of subsets of the set?

Answers

A proper subset of a set A is a subset that is strictly contained in A and excludes at least one member of A. The empty set is also a proper subset of any nonempty set. 
So there is only 1 element that a set must have if the number of proper subsets is 1/2 of the total number of subsets. 
For example: A = { 4 }
Proper subset : {  }     ( 1 )
All subsets: { } , { 4 }   ( 2 )
1 = 1/2 * 2
Answer: 1 element.

5b less than or equal to -5please show your work so that I can understand. step by step thanks

Answers

Steps for 5b less than or equal to -5: 1. Divide by 5 on both sides 2. Your answer is b is less than or equal to -1 3. With inequalities you have to find a way to get b on one side and a number other. You still have to do the same thing on both sides though. So I divided by 5 on both sides to get my answer. Hope this helps you
