No because the sum of the 2 smallest sides of a triangle must be greater than its longest side.

What is the hypotenuse of a right triangle with legs of lengths 5 and 12?
The hypotenuse of a right triangle is the square root of the sums of the squares of the lengths of the other two sides, i.e. it is c, where c2 = (a2 + b2).The hypotenuse for the example is c = [sqrt (52 + 122)] = [sqrt (25+144)]= sqrt [169] = 13.
Is 7 8 12 a right triangle?
7, 8 & 12 are the sides of the triangle.And, for a right angled triangle the Pythagoras theorem is always applicable!Pythagoras theorem states that for a right angled triangle:(Longest Side)2 = (Side-1)2 + (Side-2)2(Longest side is called as the hypotenuse).So, using data in the question:If its a right angled triangle--->122 = 72 + 82i.e. 144 = 49 + 64 => 144 = 113, which is clearly not true!Hence, the triangle with the given sides is not a right triangle.
How do you find side a if side b is 12 inches and side c is 18 inches of a right triangle?
The answer depends on whether a or c is the hypotenuse: b cannot be the hypotenuse since the hypotenuse MUST be the longest side. Suppose a is the hypotenuse. Then a2 = b2 + c2 = 122 + 182 = 144 + 324 = 468. So a = 21.63 inches (approx). Suppose c is the hypotenuse. Then c2 = b2 + a2 = 182 = 122 + a2. So a2 = 180 and a = 13.42 inches (approx).
What is the length of BC in the right triangle below with legs of 9 and 12?
Using Pythagoras' theorem the hypotenuse of the right angle triangle works out as 15.
What is the length of the hypotenuse of a right triangle that has a base of 5 inches and a height of 12 inches?
In any right triangle, the hypotense squared = the square of one side + the square of the other side. h2 = a2 + b2 Here, h2 = 52 + 122 = 25 + 144 = 169 We have h2 = 169 The square root of 169 is 13, so the length of the hypotenuse is 13 inches.
A triangle with sides of lengths 12 15 and 20 is a right triangle?
False. It can't be.In a right triangle, the sum of the squares of the two short sides is equal to the squareof the longest side.122 = 144152 = 225-------------sum = 369202 = 400, not 369.So these are not the sides of a right triangle.

Is a triangle with an interior angle of 67.38013505 degrees and a side of 12 cm opposite to it a right angle triangle?
Yes because 12 divided by tan(67.38013505) equals 5 And: 122+52 = 169 making the hypotenuse of the right angle triangle 13 cm
Why can't there be a 2 0btuse angles in a triangle?
Because 2 obtuse angles could add up to 122 and then if we have an acute angle of 60 it will add up to 182 and a triangle can only add up2 180
How do you use the Pythagorean theorem?
The Pythagorean states that a2 + b2 = c2 for a right triangle, where a and b are the lengths of the legs of the right triangle, and c is the length of the hypotenuse (the diagonal side).Say you are given a triangle with legs of lengths 3 and 4, and need to find the length of the hypotenuse. You can write the equation32 + 42 = c2, where c is the length of the hypotenuse.This gives25 = c2, and taking the square root of both sides of the equation gives5 = c, so the length of the hypotenuses in this case is 5.Another example:Say you have a right triangle where the length of one leg is 12 and the length of the hypotenuse is 13, and you need to find the length of the other leg. You can write the equationa2 + 122 = 132, where a is the length of the unknown leg.Solving:a2 + 144 = 169a2 = 25a = 5, so in this case, the length of the unknown leg is 5.
If one side of an equilateral triangle is 12Cm find the Area?
Use Pythagoras' theorem to find the triangle's altitude or height: 122-62 = 108 and the square root of this is 10.39230485 1/2*base*height = area 1/2*6*10.39230485 = 31.17691455 square units
Can you explain whether or not a triangle with dimensions in inches of VIII by IX by XII is a right angled triangle?
using Pythagoras; check if 122 = 92+82 the equation is false then no it isn't a right triangle

Use the Pythagorean theroem to determine whether a triangle with sides 5cm 12cm and 13cm?
52 + 122 = 25 + 144 = 169 = 132 This calculation confirms that the three sides of length 5, 12 and 13 cm form a right angled triangle with the side of length 13cm being the hypotenuse.
What is x in 122x equals 28?
122x = 28Divide each side by 122:x = 28/122 = 0.22951 (rounded)
