A park is shaped like a trapezoid. It has an area of 7.2 square miles. One base is 1.2 miles, and the other base is 2.4 miles long. What is the height of the park?

Answers

Answer 1

Answer: 7.2÷(1.2+2.4)=2
2÷.5=4
So the height equals 4

HELP ME PLEASE WOULD MEAN SOO MUCHA kite is a quadrilateral with two pairs of adjacent, congruent sides. The vertex angles are those angles in between the pairs of congruent sides. Prove the diagonal connecting these vertex angles is perpendicular to the diagonal connecting the non-vertex angles. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.

Answers

Answer:

Given that an image attached with this prove.

1. AD = AB, CD=CB 1. Given

2. OD = OB 2. By definition, the diagonal connecting vertec angles bisects the other diagonal

3. OA = OA 3. By reflexive property

4. triangle AOB = triangle AOD 4. By SSS congruence

5. angle AOB = angle AOD 5. By CPCTC

6. angle AOB = angle AOD = 90 6. both angles addup to 180

Whats the GCF of 18 and 30?

Answers

Well I don't know !
Let's figure it out:

-- The factors of 18 are 1, 2, 3, 6, 9, and 18 .

-- The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30 .

-- The numbers that are factors of both 18 and 30 (the 'common' ones)
are 1, 2, 3, and 6 .

-- The biggest one on that short list (the 'greatest common' one) is 6 .
