because, the formula for a hypotenuse is a^2 + b^2 = c^2
the hypotenuse is "c" and the legs of the triangle are "a" and "b"
5^2 + 6^2 = c^2 5^2=25 6^2=36 so 25+36=c^2 25+36=61 so 61=c^2 square root each side and you get "c" equaling (to the nearest tenth) 7.8

I don't see any isosceles triangle below.In general, the perimeter is the sum of the lengths of all sides. Note that in an isosceles triangle, two of the three sides have the same length.
# 4 and 6 give a hypotenuse of √(42 + 62) = √(16 + 36) = √52 = 7.2111 = 7.2 to nearest tenth. # 9 and X give a hypotenuse of 15 so 152 = 92+ X2 which gives 225 = 81 + X2 which gives 144 = X2 which gives 12 = X # 36 and Y give a hypotenuse of 39 so 392 = 362+ Y2 which gives 1521 = 1296 + Y2 which gives 225 = Y2 which gives 15 = Y # 28 and 45 give a hypotenuse of √(262 + 452) = √(676 + 2025) = √2701 = 51.9711 = 52 to the nearest tenth.

If both legs of a right triangle are the same, then it forms what is known as a "45-45-90 triangle". In this type of triangle, the hypotenuse is always √2 times more than the legs. So in this problem, with legs 3cm and 3cm, the hypotenuse is 3√2cm, or 4.243cm

The hypotenuse measures 11.4 meters in length.
Using Pythagoras' theorem the length of the hypotenuse is 17.1 inches
Yes
The simplest answer, requiring no calculation, is that BC is the hypotenuse and so the length is 12 cm.
The answer rounded to the nearest tenth is 25 meters.

Each of the other legs is sqrt 24.5 ie 4.95 to the nearest hundredth

If you mean an angle of 30 degrees then the hypotenuse is 12.5/sin(30) = 25.0 meters
