"rectangular pit similar to this

one, and 100 pounds of sand

equals 1 cubic foot, did the

council purchase enough sand

to fill the pit? If yes, how many

pounds are leftover? If no,

how many more pounds are

needed?

2. wooden boards (4.25 ft LX 1 in W X 4 in D).

2 wooden boards (3.75 ft LX 1 in W X 4 in D)

0.85% : )

step-by-step explanation:

i those same problems in math and dont know how to do them

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°.
