By making 80=2x+20 by corresponding angles in parallel lines you find x=30 because 2(30)+20=80
Distribute -
(Multiplying by 0.5 is same as divide by 2)
10x-25x+18 - 25x -10y + 3
The answer is C
The property that justifies this statement is the Symmetric Property of Congruence.
<h3>What is symmetric property of Congruence?</h3>
The symmetric property of congruence states that If an angle is congruent to another angle, then the second angle is also congruent to the first angle.
A congruent geometric shapes are shapes having the same size and shape, or matching in size and shape and their corresponding angles are equal to each other.
If shape A is congruent to shape B and A= B , then B = A
Similarly,
If angle DEF is equal to angle HJK, then with the law of symmetry property of angle HJk is equal to angle DEF.
