The length of a rectangular field is 6 feet less than 5 times its width. Its area is 306 square feet.
Find the Width and length

5X-6)+(5X-6)+X+X=252 , now lets add all the X together, and then add the whole numbers.

12X-12=252 , now lets work this by adding 12 on each side of the equation:

12X-12+12=252+12

12X=264 , divide both sides by 12.

X=22

Now lets prove X =22:

(5·22–6)+(5·22–6)+22+22=252

(110–6)+(110–6)+22+22=252

104+104+44=252

208+44=252

252=252Therefore the length is 104 feet each and the width is 22 feet each.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
