Alternate interior angles are congruent. So, angle 3 = angle 7.
We see that vertical angles are congruent. So, angle 3 also = angle 5.
Alternate exterior angles are congruent.
So, angle 3 also = angle 1.
To evaluate when plugging in numerical values for variables, simply put the numerical values in the place of the corresponding variables:


Answer: The answer is $0.42 APEX
No, on a number line, 1 would be the smallest, then 1.25 then 1.5 and then 1.6 and then 2.
So 280=1.4x so 280/1.4 is 200 .7*200 is 140 so $140
