A triangle has sides with lengths of 28 millimeters, 34 millimeters, and 43 millimeters. Is it a right triangle?

1 answer:

6 0

To find if it's a right triangle, we use the Pythagorean Theorem of a² + b² = c² where a and b are the legs of the triangle (the shorter measurements) and c is the hypotenuse (the biggest measurement).

28² + 34² = 43²
784 + 1156 = 1849
1940 ≠ 1849

No. This is not a right triangle. The sum of the squares of the shorter measurements (AKA the legs) do not equal the square of the biggest measurement.

The scale is evenly balanced. Explain how to find the weight (w) of one turtle.

Tomtit [17]

Answer: 8 units

Step-by-step explanation:

Set this up as an equation with a variable for turtles. Count up the other side of the scale (without turtles). Add up the three 1s and the 4 to get 7. Then add up all four 7s. This will get you with an equation 3t+4=28.

To solve this, first subtract 4 from both sides to get 3t=24. Now divide both sides by 3. 24/3=8. Each turtle weighs 8 units.
