REALLY URGENT. 1 3/5 divided by 2/5

4.

Step-by-step explanation:

1 3/5 = 8/5.

8/5 / 2/5          We invert the 2/5 and multiply:

= 8/5 * 5/2        The 5's cancel out:

= 8/2

= 4.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

1. 523.33 cubic inches

2. 113.04 cubic inches.

3. 17.41.

4. 16.49

i think this should be your answer
