Answer:
c is the answer
Step-by-step explanation:
i don't have one
Because the square root of 49 is seven, you now have to squared values that can be used
So 1-7^2c^2
And now, because of the negative, you will have
(1-7c)(1+7c)
Angle 1 is 68 because a straight line is 180 degrees so 180-112=68.
Angle 2 is 112 because they are opposite angles meaning they are congruent/equal.
Angle 3 is also 112 because it is adjacent to Angle 2.
The GCF is: 2x^2a
Hope this helps!
