First we have to find the length of side b. For this we use the Law of Cosines: So, we get the side b =6.92 cm. Now we can calculate the perimeter by adding the three sides of the triangle: The perimeter of the triangle is 16.92 cm. gute handcreme test

The perimeter of a triangle is the sum of its sides. Perimeter = Shortest side + 2(congruent sides) Substituting the given values: 45 = 7 + 2 x. Simplifying the equation: 2 x = 45-7 2 x = 38 x = 19. Hence, the length of the two congruent sides is 19 ft each. WebMar 1, 2024 · How do you find the height of a triangle if all sides are equal? To determine the height of an equilateral triangle: Write down the side length of your triangle. Multiply it by √3 ≈ 1.73. Divide the result by 2. That's it! The result is the height of your triangle! Are all heights of a triangle equal? box office nicky larson
