Each square below represents one whole. A square divided in 4 equal parts, all 4 of which are shaded

Another square divided in 4 equal parts, 3 of which are shaded
What percent is represented by the shaded area?

SQUARE 1:

100% ; 75%

Step-by-step explanation:

SQUARE 1:

If each square represents a whole ; the percentage of a whole = 100%

Dividing the square into 4 equal parts :

Percentage of each part :

100% ÷ 4 = 25%

Percentage represented by the shaded part:

(Percentage of each shaded part * number of shaded part)

(25% * 4) = 100%

SQUARE 2:

each square represents a whole ; the percentage of a whole = 100%

Dividing the square into 4 equal parts :

Percentage of each part :

100% ÷ 4 = 25%

Percentage represented by the shaded part:

(Percentage of each shaded part * number of shaded part)

(25% * 3) = 75%

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°
