The addition property of equality states... If a=b then a+c=b+c
Answer:
A
Step-by-step explanation:
Since DA can be considered a line the whole value of it is 180 degrees. So you do 180-105 which equals 75. You then add 75 to 67 which is equal to 142. The value of a triangle is 180 so you would do 180-142 and you would get 38. Thus, X is equal to 38 degrees.

Answer:
x = 13
Step-by-step explanation:
5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.
Then 5x + 25 = 7x - 1, and
25 = 2x - 1, and so 2x = 26 and x = 13
