A figure has been dilated from the origin by a scale factor of \frac{1}{7} 7
1

. If another dilation from the origin maps the dilated image back onto the original figure, what is its scale factor?

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°
