(7x+2)° = (9x–8)°

=>7x –9x = –8–2

=> –2x = –10

=> x = 10/2

=> x = 5

<ADB = (7x+2)°

= 7×5+2

= 37°

<BDC = (9x–8)°

= 9×5–8

= 45 –8

= 37°

<ADC = 37° + 37°

= 74°

at the end of the day vegetables at farm market sell for $2.00 a pound and a bakery costs $3.50. if Charlene wants to buy a bask

9966 [12]

10=2x+3,50 |-3,50
6,50=2x |:2
3,25=x

10=2x+7 |-7
3=2x |:2
1,5=x

You didnt say how many bakery she wants to buy, so i did one inequality for 1 bakery anderen for the maximum of 2.

Beverly drew the line AB shown below. She then constructed line DC which is the perpendicular bisector of AB.

earnstyle [38]

Answer:

Line segments are congruent due to the side-angle-side congruence postulate.

Step-by-step explanation:

DC is the perpendicular bisector of line AB, this mean that DC divides AB at 90 degrees into two equal parts at point E. Hence:

AE = BE

Also DE ≅ DE (reflexive property of congruence)

Also ∠AED = ∠BED = 90° (perpendicular bisector)

We can therefore say that triangle AED and triangle BED are congruent according to the side-angle-side congruence theorem. Therefore line AD = line BD
