the diagonals of an isosceles trapezoid are represented by 4x-47 and 2x+31. what is the value of x?

Sagot :

The diagonals of an isosceles trapezoid is congruent, therefore:

4x - 47 = 2x + 31

4x - 2x = 31 + 47

2x = 78

2x/2 = 78/2

x = 39

Check:
4 (39) - 47 = 2 (39) + 31
156 - 47 = 78 + 31
109 = 109
