Asailboat’s sail has three sides that are all the same length. each side measures x−10 units. the sail’s perimeter is 63 units. what is the value of x? enter your answer in the box. x =

In this problem, the shape of the sail is equilateral triangle. You are given that the measurement of each side is x – 10 units. The perimeter is 63 units. You have to formulate an equation to find the value of x. The formula of the perimeter is to get the sum of the measurements of the three sides of the triangle.

x – 10 + x – 10 + x – 10 = 63

3x – 30 = 63

3x = 63 + 30

3x = 93

x = 31

Therefore, the value of x is 31 and the measurement of each sides is 21 units.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
