During the day sam spent $4.85 on lunch. he also bought. two book for $7.95 each at the end of the day he had $8.20 left how much money did he start with

$28.95

Step-by-step explanation:

Sam started out with x dollars.

We represent this situation with the following formula:

x - ($4.85 + $7.95 + $7.95) = $8.20.

Then:

x - $20.75 = $8.20.

To isolate x, we add $20.75 to both sides of this equation, obtaining:

x = $28.95.

Sam started out with $28.95.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
