7x-1+7x+8+5x+2=180
7x+7x+5x+2-1+8=180
19x+9=180
19x=180-9
19x=171
19x\19=171\19
x=9
therefore,7x-1
7(9)-1
=62
therefore, 7x+8
7(9)+8
=71

Answer:7x-1=62º

7x+8=71º

5x+2=47º

Step-by-step explanation:

Total angles in a triangle equals 180º

we can equate

7x+8+7x-1+5x+2=180

collecting like terms

7x+7x+5x=180-8+1-2

19x=171

divide both side by 19

x=9

for each angles we'll sustitute x

7x+8

7(9)+8

63+8

71º

7x-1

7(9)-1

63-1

62º

5x+2

5(9)+2

45+2

47º

The common factor of given terms is x/8, which is given in option B.

<h3>What is factor?</h3>

A factor is a number that divides another number, leaving no remainder.

Here, given terms are:

 \frac{5}{8}x     and      \frac{11}{8} x

Now, factors of 5x/8 = 5 X 1/8 X (x)

        factors of 11x/8 = 11 X 1/8 X (x)

So, common factors are 1/8 and x

Thus, the common factor of given terms is x/8, which is given in option B.
