A window has an actual height of 4.5 feet. If a blueprint has a scale of 3 inches = 2 feet, find the height of the window in the blueprint.

If a blue print has a scale of 3 inches = 2 feet. The actual length of an object is 2 feet then length of the object in blue print is 3 inches. The height of the window in blue print = (4.5×1.5)= 6.75 inches.

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°
