Answer:
103
Step-by-step explanation:
Interior angles of a pentagon add up to 540
117+100+105+115+x=540
437+x=540
Subtract 437 from both sides
x=103
For this case, the first thing to do is find the scale factor.
We have then:
Substituting values we have:
Rewriting:
Then, we apply the scale factor to find the length of B'C '.
We have then:
Substituting values:
Answer:
the length of segment B'C 'is:
B'C '= 18 in
Answer:
x= -2 , y= 6 is the answer
