Which of the following will form a right triangle?
7, 24, 25
7, 23, 24
7, 25, 26 **Weegy:** 7, 24, 25 will form a right triangle according to the Pythagorean Theorem. **User:** One leg of a right triangle is 12, and the hypotenuse is 20.
The length of the other leg is a0. **Weegy:** The answer is 15. The length of the hypotenuse of a right triangle with legs of lengths 9 and 12 is 15. (9^2+12^2=15^2) (More)

One leg of a right triangle is 12, and the hypotenuse is 20.

a^2+b^2=c^2

12^2+b^2=20^2

144+b^2=400

b^2=400-144

b^2=256

b=16

Therefore, the length of the other lef is 16.

a^2+b^2=c^2

12^2+b^2=20^2

144+b^2=400

b^2=400-144

b^2=256

b=16

Therefore, the length of the other lef is 16.

The Pythagorean theorem can be used for any type of triangle.
True
False **Weegy:** The Pythagorean Theorem is one of the oldest, most well-known, and widely used mathematical relationship in history. [ It is a relationship between the three sides of a right angled triangle.
The theorem states that a^2 + b^2 = c^2, where a and b are the two shorter sides, and c is the hypotenuse - the longest side, the one opposite the right angle. ] (More)

A 25-foot flag pole casts a shadow of 40 feet. The approximate height from the top of the flag pole to the top of the shadow is 47 ft.

25^2+40^2=c^2

625+1600=c^2

2225=C^2

c=47.1699

25^2+40^2=c^2

625+1600=c^2

2225=C^2

c=47.1699
