Since you wrote 30-60-90, that is angle A is 30 degrees, and opposite the angle A is the side a = 5, the angle B = 60 degrees, and opposite the angle B is the side b, the angle C = 90 degrees, and opposite the angle C is the side c. In a right triangle, where an acute angle is 30 degrees, the length measure of the side opposite to 30 degrees angle is equal to the one half of the length measure of the hypotenuse. That is 2a = (2)(5) = 10 = c. By using the Pythagorean theorem, c^2 = a^2 + b^2, we can say that:
b^2 = c^2 - a^2
b^2 = 10^2 - 5^2
b^2 = 100 - 25
b^2 = 75
b = square root of 75
b = 8.66
b = 8.7
or you can use the Law of Sine:
a/sinA = b/sinB
5/sin 30 = b/sin 60
b = [5(sin 60)]/sin 30
b = 8.66
b = 8.7
Using Pythagoras' theorem the length of the hypotenuse is 13 units
hyp2 = leg2 + leg2 leg2 = hyp2 - leg2 leg = √(hyp2 - leg2) = √[102 - (5√3)2] = √(100 - 75) = √25 = 5
The length of the hypotenuse of a right triangle if AC equals 6 and AD equals 5 is: 7.81
The length of the diagonal of a square with sides 5 is 5√2. This is because of the properties of a 45-45-90 triangle.
9 in.
third leg 5, area 30
hypotenuse= 16.24
my name is bdub and the answer is 5 dubass
12 cm
Using Pythagoras Theorem, 102 = (5√3)2 + L2 ( L is the length of the other leg of the triangle) 100 = 75 + L2 : L2 = 100 - 75 = 25 Then L = √25 = 5. The other leg measures 5 cm
5-12-13 is a classic Pythagorean Triple.
Using Pythagoras' theorem the length of the hypotenuse is 13 units
Using Pythagoras: 5 cm
The hypotenuse must be longer than the other other leg.
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.
Information about the base length is not enough to determine the lengths of the legs other than that they must be more than 5 units.
Because it's a right angle triangle with the shorter legs being the same length use Pythagoras' theorem: 52+52 = 50 and the square root of this is about 7.071067812 units in length An exact answer is 5 times the square root of 2 which would be in surd form.
