If triangle XYZ is equilateral and the length of one side is 7.5, what is the perimeter of XYZ and what is the measure of each angle?
3 * 7.5 = P
The sum of angles in a triangle = 180 degrees.
To find the perimeter of an equilateral triangle, you multiply the length of one side by 3, since all sides of an equilateral triangle are equal.
In this case, the length of one side is given as 7.5 units. Therefore, the perimeter of triangle XYZ is:
Perimeter = 7.5 units * 3 = 22.5 units
Now, let's move on to finding the measures of each angle in the equilateral triangle.
In an equilateral triangle, all angles are congruent (equal). Since the sum of the angles in a triangle is always 180 degrees, we can divide 180 by 3 to find the measure of each angle.
Measure of each angle = 180 degrees / 3 = 60 degrees
So, in triangle XYZ, each angle measures 60 degrees.
