The perimeter of a rectangular bathroom mirror is 22 feet. It is 2 feet tall. How wide is it?

9 feet wide

Step-by-step explanation:

22- 2(2) = 18 you have to subtract both heights

18/2 = 9 take the remainder and divide by two for both widths of rectangle

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°
