Susan has a 12-inch board for constructing a wooden chair. The directions say to use a board that is 29 centimeters long. Is her board long enough to cut?

Step-by-step explanation:

To know if Susan has enough board to construct the wooden chair, we need to transform from inches to centimeters.

We know that 1 inch is equal to 2.54 centimeters.

Using the rule of three, we have

Which means Susan has a board with 30.48 centimeters long, and she only needs 29 centimeters.

Therefore, Susan has enough bord to construct the wooden chair.

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°
