Before you can add or subtract fractions with different denominators.you first have to find common denominators. subtract the numerators and reduce fraction.
Adding fractions make sure numbers are same add the numerators and put it over the denominator,simplify the fraction if needed

<h3>C. 113°</h3>
Step-by-step explanation:
(7x - 1) + 79° = 21x + 8
• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.
NRS = 21x + 8
Answer:
(B)15,36,39
Step-by-step explanation:
To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.
By Pythagoras Theorem: 
In 15,30,35
In 15,36,39
In 15, 20, 29
In 5,15,30
We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.
The Absolute value of 7 is seven since it is only seven did-gets away from zero.
