A triangle with sides a, b, and c whose circumference is 26 cm is true: ratio a:b is 4:3, and ratio b:c is 1:2. Find the lengths of the sides of this triangle. - Magnitudes 19623
Calculate the magnitudes of the interior angles of a triangle if you know that these are in a 2:3:5 ratio. - Circumference 15873
The sides of the triangle are in a ratio of 3:4:6. One side of it measures 21 cm. Calculate its circumference. - Triangle sides - natural
In triangle ABC, side a = 30 cm b = 7 cm. The length of the third side in cm is a natural number. What is the least and what is the greatest length that side c can have? - The triangle - sides
The two sides of the triangle have side lengths a = 6cm and b = 13cm. Then the following applies to the length of the third side c: (A) 7 - Sides in ratio
The sides of the triangle are in a ratio of 2:6:5. Find the dimensions of the remaining sides if the longest side is 32 cm. - Perimeter of a triangle If the perimeter of a triangle is 6 2/3 cm and the lengths of two sides are 2 1/2 cm and 3 1/3 cm, find the length of the third side.
- The two
The two angles of a triangle are 78° and 82°. So, what is the measure of the remaining third angle? - The angles ratio The angles in the ABC triangle are in the ratio 1:2:3. Find the angles' sizes and determine what kind of a triangle it is.
