Determine if the three given side
lengths form a right triangle.
10 cm, 15 cm, 20 cm

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

Hope this helped :)

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
