The figure below shows a triangular piece of cloth: triangle abc has angle abc equal to 90 degrees and angle bac equal to 35 degrees. length of ac is 8 inches. what is the length of the portion bc of the cloth? 8 cos 35° sin 35 degrees divided by 8 cos 35 degrees divided by 8 8 sin 35°

answer:

the length of the portion bc of the cloth is:

step-by-step explanation:

we are given a right angled triangle abc such that ∠abc=90° , ∠bac=35°

also we are given length of side ac=8 inches.

we are asked to find the length of the portion bc of the cloth.

from the figure we could clearly see that the side bc is the perpendicular for δabc.

now using the trignometric formulae

here  

hence .

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:
