A pyramid has a a rectangular base of length (3x+1)cm and width x cm. It also has a perpendicular height of 12cm. The volume of the pyramid is 96cm3. Given that the volume of a pyramid is one third of the area of the base multiplied by the perpendicular height, find the dimensions of the base of the pyramid

if you was gonna solve for a, a is a   < -12

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°.

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
