Using the Pythagorean Theorem, we can find your answer.
a^2 + b^2 = c^2
9^2 + 40^2 = c^2
81 + 1600 = c^2
1681 = c^2
√1681 = c
41 = c
Your hypotenuse would be 41 feet.

The legs of a right triangle have the same length and the hypotenuse is 30ft?
The legs of a right triangle have the same length and the hypotenuse is 30 ft, each leg would be of length 21.21 ft.
If the legs of a right triangle are 4 ft and 3 ft find the length of the hypotenuse?

If side a equals 76.4 ft and side b equals 39.3 ft what is the measure of angle A?
I will assume that this is a right triangle and neither side length is the hypotenuse. In the case that this is a right triangle and neither side length given is for the hypotenuse, you would use tangent to solve for your angle measure. tan(Q) = the length of the side opposite of Q/the length of the side adjacent to Q. So for this answer: **NOTE: Side a is traditionally the side opposite to angle A.** tan(A) = a/b *where b is not the hypotenuse => tan(A) = 76.4/39.3 tan(A) = 1.94402... A = arctan(1.94402...) *arctan is the same thing as inverse tangent or tan^(-1) A ~= 62.78 Degrees * ~= means approximately. ***Extra stuff: tan = opposite/adjacent sin = opposite/hypotenuse cos = adjacent/hypotenuse
What is the length of the hypotenuse of a right triangle with legs that are 6 feet long and 7 feet long respectively?
The length of the hypotenuse is sqrt (85) ; a little over 9 ft.
If a circle has a diameter of 40 ft what is the length?
circumference? 40 pi ft.
What is the length of the hypotenuse 30 ft x 40 ft?
50 ft providing that it is a right angle triangle.

If one leg of the isosceles right triangle is 2 feet long find the length of the hypotenuse?
Isosceles triangles have two sides which are the same length and two angles which are equal. So if your right triangle has one side of length 2 feet, which is not the hypotenuse, then the remaining side must also be 2 feet long. We know that the square of the length of the hypotenuse is equal to the squares of the other two sides. 2 squared is 4. So the squares of the two sides are 4 + 4 which equals 8. Now we just find the square root of 8, which is 2.8284... So the length of the hypotenuse is 2.83 Feet (to two decimal places). Or, In a right isosceles triangle, the two base angles equal 45°. Since the length leg is 2 ft, then the hypotenuse length would be equal to 2√2 or approximately to 2.83 ft. sin 45° = leg/hypotenuse hypotenuse = 2/sin 45° hypotenuse = 2/(√2/2) hypotenuse = 4/√2 hypotenuse = 4√2/2 hypotenuse = 2√2 °
If a circle has a diameter of 40 ft what is the length?
circumference? 40 pi ft.
If a hypotenuse of a triangle is 28 ft long and another side is 50 ft long what is the length of the other leg?
The hypotenuse is always the longest side so the triangle, as described, cannot exist.
The side lengths of a rectangular room are 6 ft and 8 ft. The room is going to be split in half along the hypotenuse of a triangle using string. Find the length of the piece of string needed.?
Using Pythagoras' theorem the length of the hypotenuse is 10 feet which will be the length of the string needed
What is the area in square feet of a rectangle with the length 40 feet and the width 50 feet?
The area formula is: Area = length x width Let: length = 40 ft width = 50 ft Then: A = 40 ft x 50 ft = 2000 ft²
A right angle triangle has an angle of 16.5 degrees. and a rise of 40 feet then how many feet is the hypotenuse?
sin(angle) = opposite/hypotenuse → hypotenuse = opposite/sin(angle) opposite = rise → hypotenuse = 40ft / sin 16.5° ≈ 140.84 ft
How does one figure square feet?
Length in feet times width in feet equals area in square feet. L=4 ft, W=10 ft; 4x10=40; Area=40 square feet.
