We have the numbers 4, 6, 9, 13, and 15. What is the probability that these will be the lengths of the sides of the triangle? (Consider only scalene triangles.) - Circumference 5647
The circumference of the isosceles triangle is 7.8 cm, and the base length is 34 cm. How long are his shoulders? - Difference 4050
Calculate the size of the interior angles of a triangle if the size of the second angle is 120 degrees less than twice the size of the first angle and the size of the third angle is equal to the difference between the sizes of the first and second angles. - Magnitudes 3304
In triangle ABC, the interior angle at vertex B is 10 degrees greater than the angle at vertex A, and the angle at vertex C is three times greater than the angle at vertex B. Calculate the magnitudes of the interior angles of the triangle. - On a mass
The forces F1, and F2 with magnitudes of 40N act on a mass point M. Their resultant has a magnitude of 60N. Determine the angle that the forces F1 and F2 make. - Christmas napkins
The girls embroidered Christmas napkins. Each napkin had a triangle shape with 5 dm, 60 cm, and 800 mm sides. How many cms did the girls sew if they made 15 napkins? - Trigonometric 50551
