How far from the base of the house do you need to place a 15 foot ladder so it exactly reaches the top of a 12 foot tall wall?

How far from the base of the house do you need to place a 15 foot ladder so it exactly reaches the top of a 12 foot tall wall?

9 foot

What is the longest line in a triangle?

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.

What does the letter C stand for in the formula a2 b2 c2?

a c Pythagorean Theorem: a2 + b2 = c2. b. NOTE: The side “c” is always the side opposite the right angle. Side “c” is called the hypotenuse.

What side is C on a triangle?

hypotenuse

How do you solve A2 B2 C2?

The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

What are the sides of ABC?

The three sides for triangle ABC shown above, written symbolically as △ABC, are line segments AB, BC, and AC. A vertex is formed when two sides of a triangle intersect. △ABC has vertices at A, B, and C. An interior angle is formed at each vertex.

Does 20 25 and 15 represent a right triangle?

The largest length is always the hypotenuse. If we were to multiply any triple by a constant, this new triple would still represent sides of a right triangle. Therefore, 6, 8, 10 and 15, 20, 25, among countless others, would represent sides of a right triangle.

Does 5 12 and 13 form a right triangle?

The 5 12 13 triangle is an SSS special right triangle with the ratio between its side lengths as 5, 12, and 13. It is a common Pythagorean triple that is worth memorizing to save time when dealing with right triangles. The other common SSS special right triangle is the 3 4 5 triangle.

Does 7 9 and 11 make a right triangle?

Answer: False – a triangle with side lengths 7, 9, and 11 is not a right triangle.

Can segments with lengths of 15 20 and 36 form a triangle?

Can the segments lengths of 15, 20, and 36 form a triangle? If so, would the triangle be acute, right, or obtuse? The side lengths do not form a triangle.

Will the lengths 4/9 and 5 form a triangle?

The lengths 4, 5, 10 also cannot make a triangle because \begin{align*}4 + 5 = 9\end{align*}. The arc marks show that the two sides would never meet to form a triangle. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.

Could 10.7 cm 3.2 cm and 5.5 cm be the side lengths of a triangle?

NO. The sum of the lengths of any 2 sides of a triangle must be larger than the length of the 3rd side.

Is it possible to have a triangle with the following sides 3 cm 6 cm 7 cm?

In a triangle, the sum of the lengths of either two sides is always greater than the third side. Given that, the sides of the triangle are 3 cm, 6 cm, 7 cm. Hence, this triangle is possible.
