Can 15cm 6cm and 9cm form a triangle?
No. The sum of the lengths of any two sides of a triangle must be greater that the third. Here 6 + 9 = 15, not > 15.
An isosceles triangle has two equal sides that are 15cm long and two equal angles of 62 degrees calculate the length of the third side?
first find the unknown angle, 180o - (62o+62o) = 56o next use the law of sines to find the other side: sin 62o / 15cm = sin 56o / X Solving for x, X = 14.08 cm
Find the altitude of a triangle whose area is 45cm squared and 15cm?
The height or altitude of triangle: (2*45)/15 = 6cm Check: 0.5*15*6 = 45 square cm
What is the surface of 15cm x 15cm?
15*15 = 225 square centimetres.
What is the total area of a quadrilateral?
15cm 12cm
What is a triangle with sides 11cm 15cm 11cm?
Isosceles
Can you construct a triangle that has side lengths 11cm 12cm and 15cm?
Yes
Is 7cm 11cm 15cm a right triangle?
To determine if the given measurements form a right triangle, we can use the Pythagorean theorem. In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. So, in this case, we would check if (7^2 + 11^2 = 15^2) holds true. Calculating this, we get (49 + 121 = 225), which simplifies to (170 \neq 225). Therefore, the given measurements do not form a right triangle.
What is the area of a right triangle with sides of 8cm 15cm 17cm?
60 cm2
If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
what is 40mm - 15cm?
40mm - 15cm = 25
What is the length of the hypotenuse of a right triangle where the two sides are 15cm and 15cm long?
Using Pythagoras' theorem: 15 times the square root of 2 cm in length
What is 40MM subtract 15Cm?
25
How many triangles have the perimeter of 15cm?
2
What shape has sidelines of 5cm 8cm and 15cm?
Well, assuming it doesn't have any other sides, it's a scalene triangle.
Can 15cm 6cm and 9cm form a triangle?
No. The sum of the lengths of any two sides of a triangle must be greater that the third. Here 6 + 9 = 15, not > 15.
What is the ratio of the length of a side of an equilateral triangle to its perimeter?
Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified. Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.
