The answer is A because you turn the fraction in a decimal then divide by 5
Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
Answer:
Point D is invariant
Step-by-step explanation:
A geometry tool such as GeoGebra can help with this effort.
Using the geometry tool, I found it easier to move points P and Q, rather than trying to move lines m1, m2, and n. That has the same effect.
The problem setup has points A, B, and C remaining where they started. I was a little surprised to see that point D also remains in the same location. (I could not see any obvious reason why. Perhaps proportions are involved.)
Attached are two different sets of m1, m2, and n for the same A, B, C. You can see that point D remained in the same place. "Quadrangle" PQRS is colored in both figures.
