8
created by the intersection of lines
C
and
D
.
Use complete sentences to explain how the special angles created by the intersection of lines
C
and
D
can be used to solve for
y
.
Solve for
y
and find the measures of
∠
7
and
∠
8
.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

answer:   2 multiplied by x =24

step-by-step explanation:

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
