Question

Someone, please help me with this.

Answer 1

Answer:

x = 14°

Step-by-step explanation:

Since the two angles lie on a straight line the sum of their angles is equal to 180°.

To find x add up the two angles and equate it to 180° and solve for x

That's

7x - 1 + 6x - 1 = 180

13x - 2 = 180°

Move 2 to the right side of the equation

That's

13x = 180 + 2

13x = 182

Divide both sides by 13

That's

$\frac{13x}{13} = \frac{182}{13}$

We have the final answer as

x = 14°

Hope this helps you

Answer 2

Answer:

$\large\boxed{x=14}$

Step-by-step explanation:

Because the angles are adjacent to each other and form a straight line, they are supplementary angles. Supplementary angles add up to 180 degrees, therefore, you can add the two angle measures together and set them equal to 180.

(7x - 1) + (6x - 1) = 180 combine like terms

13x - 2 = 180 add 2 to both sides

13x = 182 divide by 13 on both sides

$\boxed{x=14}$
