Apply the Pythagorean Theorem to find the distance between points B and C. A) 18 units B) 55 units C) 64 units D) 73 units
nadya68 [22]

Answer:

BC=\sqrt{73}

Step-by-step explanation:

Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.

If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.

If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.

Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

BC=hyp=\sqrt{8^2+3^2} =\sqrt{64+9} =\sqrt{73}

UkoKoshka [18]
260 divided by 90 is 2.8 and you would probably want to round that up so 3 quarts
