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

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
