Which of the following sets could be the sides of a right triangle?

For this question you just have to check that when you pluggin the sides into the pythagorean theorem both sides are equal to each other:

a^2+b^2 = c^2 (where c is the longest side)

1)

2^2+3^2 = (sqrt(13))^2

4+9 = 13

13 = 13 YES, RIGHT TRIAGLE (pythagorean theorem holds true)

2)

5^2+5^2 = (2sqrt(10))^2

25+25 = 40

50 =! 40 NO, NOT RIGHT TRIANGLE (pythagorean theorem does NOT hold true)

3)

5^2+12^2 = 15^2

25+144 = 225

139 =! 225 NO, NOT RIGHT TRIANGLE (pythagorean theorem does NOT hold true)

therefore, the first set is the only one which could contain the sides of a right triangle.

Right Triangle Calculator

Right Triangle Calculator – A right triangle is a type of triangle that has one angle that measures 90°. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equationSet the user's input to the variable you created representing the first side of the triangle. Use a series of nested if / else statements to determine if the triangle having side-lengths as set Checking to make sure the sides are non-negative is a great idea. You could probably reasonably rule out…We can find an unknown side in a right-angled triangle when we know: one length, and. one angle (apart from the right angle, that is). The depth the anchor ring lies beneath the hole is 18.88 m. Step By Step. These are the four steps to follow: Step 1 Find the names of the two sides we are using…

code generation – C++ program on determining triangle – Stack Overflow – Which of the following sets of three numbers could be the side lengths, in yards, of a right triangle containing a 45° angle? Here, even if we forgot the 45-45-90 ratios, we can eliminate any choice that doesn't meet the Pythagorean theorem, since the question tells us we're dealing with a right triangle.If a triangle is a right triangle, then the lengths of its sides satisfy the Pythagorean Theorem, a2+b2=c2. To determine which choice is correct, test each set of values by substituting them into the Pythagorean Theorem. Start with the first set of numbers: 3, 13, and 14. 32+132=142 9+169=196 178…Step-by-step explanation: Through the use of the Pythagorean Theorem your father ask you to make a lay out of a rectangular garden he is planning to make in your backyard. the area of a rectangular garden must be 48ft a … ng had the length of 4 ft more than twice the width. find the…

Finding a Side in a Right-Angled Triangle – Construct a right angled triangle whose hypotenuse measures 5 cm and one of the other sides measures 3.2 cm. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries.which of the following sets could be the sides of a right triangle? which of the following equations is quadratic? (x+3)(x+4) = 5. find the line of symmetry for the parabola whose equation is y = 2x^2 – 4x + 1.Lengths of triangle sides using the Pythagorean Theorem to classify triangles as obtuse, acute or right. You can directly assign a modality to your classes and set a due date for each class. Determine if each of the following lengths make a right triangle.
