30%

We have to find the percentage of the the shaded portion. for doing this we can express it in fractional form and then multiply it with 100. We can see that 6 out of 20 boxes are shaded.

Thus it becomes 6/20.

to find the percentage

6/20 × 100 = 30%

therefore we get that 30% of the large rectangle is shaded

pls give brainliest for the answer

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°
