What is the value of x?

a)20
b)35
c)60
d)70

For this case we have to define by opposite angles the vertex that:

Subtracting 3x on both sides of the equation:

Subtracting 40 from both sides of the equation:

Dividing between -2 on both sides of the equation:

So, we have that

i will take them

step-by-step explanation:

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
