You want to divide a square piece of paper into two equivalent triangle if the square measures 20m in each side what will the third side measure

20 √2 cm or 28.3 cm

Step-by-step explanation:

Folding a paper diagonally will result in two triangles. You know each side of the square piece of paper is 20 cm, so a^2 and b^2 is 20 cm.

Use the formula ‘a^2 + b^2 = c^2’

20^2 + 20^2 = c^2

400 + 400 = 800

√800 = 20 √2 or 28.3 cm

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
