Show your calculation below:In the diagram of AABC below, DE is parallel to AB, CD = 15,
AD = 9, and AB = 40.
The length of DE is
(1) 15
(2) 24
(3) 25
(4) 30
So your answer is
What is the relation between ACDE and ACAB?
What information in the question helps you get that
conclusion?
Answers
Answer:
DE=25
Angles CDE & CAB are equal since they are alternate angles.
Step-by-step explanation:
Triangle CDE is an reduction of triangle CAB.
Reduction Ratio=
Angles CDE,CAB relationship- the two angles fall on opposite relative sides of two parallel lines are therefore equal.

The angle supplementary to the angle 39° Mabel measured is C. 129°.
What are supplementary and complementary angles?
When the sum of the two angles is 180° they are said to be supplementary.
When the sum of the two angles is 90° they are said to be complementary.
Given, Mabel measured an angle on her math worksheet with her protractor. The angle measured 39°.
Therefore, The angle supplementary to the angle she measured is,
= (180 - 39)°.
= 129°, As the sum if the sum of two angles are supplementary their sum is
180°.

Final answer:
The best description for the algebraic expression x/3 - 15 is 'A number divided by three minus fifteen'. This description accurately represents the mathematical operations indicated in the expression.
Explanation:
The algebraic expression x/3 - 15 best described by: 'A number divided by three minus fifteen.' This is a result of the mathematical symbols represented in the expression. The expression x/3 is read as 'a numberdivided by three,' and the '- 15' translates to 'minus fifteen.' Therefore, the entire expression, x/3 - 15, describes a scenario where a number is divided by three, and then fifteen is subtracted from the result.

Answer:
Range of f=R
Step-by-step explanation:
We are given that a function
We have to find the range of given function.
The given function is linear function because the degree of function is 1.
When the degree of function is 1 then the function is called the linear function.
The domain of linear function is a set of real numbers because it can be defined for all real values of x.
Domain of given function =R
When we substitute the real value of x in given function then we get a real number also.
Therefore, the range of f=R
