If the lengths of the legs of a right triangle are 5 and 7,
then the length of the hypotenuse is
sqrt( 52 + 72 ) = sqrt( 25 + 35 ) = sqrt( 60 ) = 7.746(rounded)
Note:
This only works with a right triangle.

What is the length of the hypotenuse of a right triangle with legs of lengths 5 and 7?
To answer this question, use the pythagorean theorem: a^2+b^2=c^2, where a and b are leg lengths and c is the length of the hypotenuse. Then isolate c, the length of the hypotenuse. c=sqrt(a^2+b^2) At this point, simply plug in the leg lengths, 5 and 7, in for a and b. c=sqrt(5^2+7^2) c=sqrt(25+49) c=sqrt(74)
How many 1.4 metre lengths can be cut out from a 7 metre piece?
Five lengths because 7/1.4 = 5
Could 4 7 7 be side lengths of a triangle?
Yes and the given lengths would form an isosceles triangle.
The lengths of 2 sides of an isosceles triangle are 7 and 5 what are all the possible lengths of the third side?
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
What are the lengths of the tangent lines from the point 7 -2 to the circle x2 plus y2 -10y -24 equals 0 on the Cartesian plane?
Equation of circle: x^2 +y^2 -10y -24 = 0 Completing the square: x^2+(y-5)^2 = 49 Center of circle: (0, 5) Radius of circle: 7 Distance from (7, -2) to (0, 5) = sq rt of 98 and is the hypotenuse of a right triangle Using Pythagoras: theorem: distance^2 minus radius^2 = 49 Therefore lengths of tangent lines are square root of 49 = 7 units

How many 1.4 metre lengths can be cut out from a 7 metre piece?
Five lengths because 7/1.4 = 5
How many 1.4 m lengths can be cut out from a 7 m piece?
There can be 5 pieces.
The length of the hypotenuse of a right triangle with legs of 7 cm and 24 cm?
The length of the hypotenuse of a right triangle with legs of 7 cm and 24 cm is: 25 cm
What is the length of the hypotenuse of a right triangle if the lengths of the legs are 24 inches and 7 inches?
The Pythagorean theorem states that the length of the hypotenuse of a right triangle is the square root of the sum of the squares of the other two sides.[(24 in)^2 + (7 in)^2]^(1/2) = 25 in
If a rectangle has a perimeter of 14 meters and a diagnol of 5 meters what is the area of the rectangle?
A rectangle must have four right angles and parallel sides. Therefore, you can divide the rectangle into two equal right angle triangles along the diagonal. As the perimeter is the sum of all of the sides of the triangles that aren't a hypotenuse, each of one of the triangles' legs length would add up to to half the perimeter of the rectangle i.e. 7. The length of the hypotenuse is 5. With basic trigonometry you should recognise that this is a pythagorean triple, or in otherwords the hypotenuse is 5 and the lengths of the 'legs' are 3 and 4 Now that you now know the lengths of the legs of the right angle triangles, and the legs correspond with the sides of the rectangles, you can now calculate the area: A = 4*3 = 12 m2
What is the perimeter of a grid 7 by 5?
7 +5+7+5 because you need to add up the lengths of all the sides.
Could 4 7 7 be side lengths of a triangle?
Yes and the given lengths would form an isosceles triangle.
What is the length of a hypotenuse of an isosceles triangle with legs of 5 feet each?
The word hypotenuse implies this is a right triangle. An isosceles right triangle has sides of 1, 1, and sqrt(2), or multiples of those. So the hypotenuse = 5*sqrt(2), which is approximately 7.07 feet or about 7 ft and 7/8 inch.
The hypotenuse if legs are 7 and 24?
25. 7, 24, 25 is a Pythagorean Triangle, just as 3, 4, 5 is
The lengths of 2 sides of an isosceles triangle are 7 and 5 what are all the possible lengths of the third side?
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
The legs of a right triangle are 5 and 7 centimeters long respectively What is the length of the hypotenuse?
8.6cm
