How do you write the inverse converse and contrapositive of the statement a triangle is equilateral if it has three sides with the same lenghts?

The original statement is: "If a triangle has three sides of the same length, then it is equilateral." Inverse: "If a triangle does not have three sides of the same length, then it is not equilateral." Converse: "If a triangle is equilateral, then it has three sides of the same length." Contrapositive: "If a triangle is not equilateral, then it does not have three sides of the same length."

What is the height of an equilateral triangle with a length of x?

Cutting the equilateral triangle in half results in two right triangles each with a base of length x/2, and angles of 30, 60, and 90 degrees. Using the lengths of sides of a 30-60-90 triangle it can be found that the height is (x/2)√(3), which is the same as the height of the equilateral triangle.So the height of the equilateral triangle is x√(3) / 2.

What is the area of an equilateral triangle with sides of ten inches and height of seven inches?

There is a problem with your question, namely that such a triangle does not exist. An equilateral triangle with sides of length 10 would have a height of 5 * (root 3), which is approx 8.66 (not 7 as the question states). An equilateral triangle of side length 10 inches would have an area of 25*(root 3), which is approx. 43.3 inches2.
