The base of a rectangle is 4 more than the height. the area of the rectangle is 15 square inches. what are the dimensions of the rectangle to the nearest tenth of an inch?

The dimensions are 6.4 by 2.4. I set up a quadratic equation and solved using the quadratic formula. Take a look at my picture if you want to know how I set the equation up

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°
