You mow 1/3 of the lawn. your sister mows 2/7 of the lawn. what fraction of the lawn is mowed?

13/21 of the lawn is mown.

Step-by-step explanation:

First, convert 1/3 to 7/21 by multiplying both the numerator and the denominator by 7. Then, convert 2/7 to 6/21 by multiplying both the numerator and the denominator by 3. Last, add 7/21 to 6/21 to get an answer of 13/21.

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°
