I don’t know what this is or have any idea how to do it can someone help and explain

w = -13

Step-by-step explanation:

Since BC bisects <ACD, then <ACB = <BCD.

We know that those two angles must equal 108 because 180-72=108.

Half of 108 is 54.

<BCD is the same as the same as the angle that equals 2w+80, so

2w+80=54

2w=54-80

2w=-26

w=-13

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.

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
