The length of a rectangle is 7ft more than the width the perimeter is 58 ft find the lengeth and width of the rectangle

The perimeter is the sum of the sides.  Let's call the width length w so the length l is w+7

58 = w + w+7 + w + w+7 = 4w+14

44 = 4w

w = 11

l = w + 7 = 18

Length 18 width 11

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°

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
