Write an equation that you can use to solve for the height of the triangle (x). Notice that the perimeter is 48 feet. A. 48 = 12 + 20 + x
B. 48 = 12(x)/2
C. 48 = 12(x) (20)
D. 48 = 12 + 20 - x

Step-by-step explanation:

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°
