Upper triangle: 12x +7x + angle of vertex = 180°
Lower triangle: 7x+6x+1 + angle vertex =180°
Notice than the angles at the vertex are equal

Then: 12x+7x+angle of vertex =7x+6x+1+angle of vertex
19x =13x+1
6x=1 & x=1/6

6x+1 = 12x because the Z angles are the same

Solve this and you get:

1 = 12x - 6x => x = 1/6

Answer:

Step-by-step explanation:

The difference between 10 and a number is (10 -N).

The sum of 8 and a number is (8 +N).

In this context, "is" means "equals," so we have ...

Solve for y.<br> y y<br> —— = ——<br> P-9 P+9

Veronika [31]

Answer:

y = 0

Step-by-step explanation:

Subtracting the right side gives ...

$\dfrac{y}{P-9}-\dfrac{y}{P+9}=0\\\\y\left(\dfrac{(P+9)-(P-9)}{P^2-81}\right)=0\\\\y\left(\dfrac{18}{P^2-81}\right)=0\\\\\boxed{y=0}$

The factor multiplying y cannot be zero, so y must be zero.
