Question

help understanding would be greatly appreciated

Answer 1

set them equal to each other
2x-3=71 solve for x

Answer 2

I think they are called alt. ext. angles

Answer 3

When a line intersects two parallel lines, it is called the transversal. It creates alternate exterior and interior angles. Alternate angles are equal to eachother. It also creates adjacent angles which are supplementary, and they add up to equal 180 degrees.

Answer 4

Hmm still kinda confusing :(

Answer 5

angle 11 is equal to angle 9 according to alt ext angles
2x-3=71
add 3 to both sides
divide by 2 to both sides
and you will have your x value

Answer 6

Oh so there bringing algebra in geometry

Answer 7

i take it its the same for part 2 of the question ?

Answer 8

Yes, that is why Algebra is taught first, then geometry,
as you go up in mathematics all skills are brought forth
Calculus is a big punchbowl of mathematics
It is like IRON CHEF

Answer 9

part 2 is the same

Answer 10

Ok cool xD heedfully i don't mess up
