What are the missing reasons in the proof abcd with diagonal bd prove abd = cdb

Proving That a Quadrilateral Is a Parallelogram: 1. equilateral 2. 128.6  3. 21   4. 720 degrees  5. x = 99 degrees  6. 96 degrees 7. 5 sides

Step-by-step explanation: 8. find the values of the variables x, y, and z in the parallelogram [109 + 33 + y = 180] [142 + y = 180] [y = 180 - 142] [y = 38] [z = 109 because opposite angles are congruent.] [x = 33 because both are alternate angles from each other.]

9. find the values of x and y.

DH = HF  x + 1 = 3y, y = (x + 1)/3  

GH = HE  3x - 4 = 5y + 1, y = (3x - 5)/5

solve for x --> (x + 1)/3 = (3x - 5)/5

5x = 9x - 20

5x - 9 = -9x - 20

4x = 20

4x/4 = 20/4

x = 5

solve for y

y = (x + 1)/3

y = (5 + 1)/3

y = 6 / 3

y = 2

10. OL = NM  3y - 6 = x - 5, 3y = x - 6 + 5, 3y = x - 1, y = 1/3x - 1/3

ON = LM  8x - 8 = 7x + 4, 8x + 8 + 7x + 4 + 8, 8x = 7x + 12, x = 12

y = 1/3(12) - 1/3

y = 4 - 1/3

y = 11/3

11. reasons 3. definition of parallelogram 4. alternate interior angles 5. reflexive property 6. ASA

12. Yes, both pairs of opposite angles are congruent.

13. Statements: 2. SV is II to TU 3. SVU equals UTS and VUT equals TSV Reasons: 7. Transversal parallel lines 8. Two pairs of angles are congruent

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
