Answer:
We know that opposite angle are congruent.
So, We found out that x = 7,
So, Putting x = 7 in 10x+10
So, The measure of angle 10x+10 is 80.

i hope this helps :)
Multiply both the numerator and denominator by , which is called the "conjugate" of :
Why do we pick this number? Recall the difference of squares factorization:
Now replace and . Then
So in your fraction, you end up with
Finally, just expand the product.
