In an equilateral triangle, the measure of each angle is 60 degrees. Then the value of x and y is 17/3 and 65.What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.In trianlge ΔMNP, PM = 3x - 4, MN = 14, ∠N = 5y - 5.In an equilateral triangle, all the sides and all the angles are equal.MN = NP = PM∠M = ∠N = ∠PThen we have PM = MN3x - 4 = 14 x = 17/3We know in an equilateral triangle, the measure of each angle is 60 degrees. Then we have ∠N = 605y - 5 = 60 5y = 65 y = 13More about the triangle link is given below.
