You need more information.
If you know one of the missing sides you can use Pythagoras's theorem to calculate the other side. If you know one of the angles, you can use the sine rule. But with no more information you cannot go any further.
Using Pythagoras' theorem it is 15 feet
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
If the sides of a right angle triangle are 6 feet and 8 feet then by using Pythagoras' theorem the hypotenuse will be 10 feet
This is merely a doubling of the 5-12-13 triangle. The sides are 10 and 24 ft.
No. 602 = 3600, 302 + 502 = 3400 so Pythagoras' Theorem is not satisfied.
A triangle with sides measuring ; 4 feet , 6 feet and 9 feet is a right triangle. A triangle is a right triangle as long as it has one 90 degree point.
The hypotenuse of a right triangle with sides of 9 feet and 13 feet is: 15.81 feet
Using Pythagoras' theorem it is 15 feet
If you divide the equilateral triangle into two right angle triangles then the hypotenuse will be 12 feet.
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
If the sides of a right angle triangle are 6 feet and 8 feet then by using Pythagoras' theorem the hypotenuse will be 10 feet
This is merely a doubling of the 5-12-13 triangle. The sides are 10 and 24 ft.
The sides of the triangle measure 3 feet, 4 feet, and 5 feet. 5 feet is the longest side.
No. 602 = 3600, 302 + 502 = 3400 so Pythagoras' Theorem is not satisfied.
Using Pythagoras it works out as 24*square root of 2 which is about 34 feet
About 62 Feet squared
Yes.
