The diagonals are congruent.
hope this helped.
Answer:
x = 6.5
Step-by-step explanation:
* since it's a triangle ALL the angles inside should give you 180° * Equate everything to 180°
8x + 10x - 10°+ 10x + 8° = 180°( sum of angles on a triangle)
28x - 2° = 180° * group like terms*
28x = 182°
x = 6.5
Step-by-step explanation:
an expression a = a is always true for all possible values of the variable.
therefore, this has an infinite number of solutions.
