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?
No. 7 squared plus 11 squared does not equal 15 squared.
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.
