Given: AD = BC and AD || BC
bearhunter [10]

Answer:

ABCD is a parallelogram.

Step-by-step explanation:

A parallelogram is a quadrilateral that has two parallel and equal pairs of opposite sides.    

From the given diagram,

Given: AD = BC and AD || BC, then:

i. AB = DC (both pairs of opposite sides of a parallelogram are congruent)

ii. <ADC = < BCD and < DAB = < CBA

thus, AD || BC and AB || DC (both pairs of opposite sides of a parallelogram are parallel)

iii. < BAC = < DCA (alternate angle property)

iv. Join BD, line AC  and BC are the diagonals of the quadrilateral which bisect each other. The two diagonals are at a right angle to each other.

v. <ADC + < BCD + < DAB + < CBA = 360^{0}  (sum of angles in a quadrilateral equals 4 right angles)

Therefore, ABCD is a parallelogram.

) What would the value of c be when
jasenka [17]

The value of c is 233.3

Step-by-step explanation:

Given equation is:

\frac{18}{20}c-250=-40

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210

Multiplying by 20 on both sides

20*\frac{18}{20}c=210*20\\18c=4200

Dividing both sides by 18

\frac{18c}{18}=\frac{4200}{18}\\c=233.3333

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3
