the total perimeter length would just be to add them up, 13+4+21= 38ft
Yes. The triangle with sides 7 cm, 8 cm, 13 cm is obtuse (the angle opposite the side of 13 cm is 120o) and scalene as none of the sides are equal.
Yes.eg The triangle with sides 7 cm, 8 cm, 13 cm is both obtuse (angle opposite side of 13 cm is 120o) and scalene (none of the sides are equal).
13 in
Any triangle whose sides form a Pythagorean triple, eg 3-4-5 or 5-12-13
Yes! A scalene triangle is one where none of the 3 sides are equal. An obtuse triangle is one where one of the angles is greater than 90 degrees. So, for example, a triangle whose angles were 100, 45 & 35 (the 3 must equal 180) will be obtuse and scalene.
To find the length of the base, you would have to multiply 182 by 2, then divide that by 13. The answer would be 28 feet for the length of the base.
The area is approximately 71.2 units2
Using Pythagoras' theorem the length of the hypotenuse is 13 units
If it's a right angle triangle then the other leg will also be 13 units in length and use Pythagoras' theorem if you need to find the length of the hypotenuse.
The area of triangle is : 78.0
Use Pythagoras to find the perpendicular height of the triangle: 132-52 = 144 and the square root of this is the height of the triangle which is 12 cm Area = 1/2*12*10 = 60 square cm
No because otherwise it would be a right angle triangle.
