Two parallel lines are crossed by a transversal.
2 answers:
<u>Part a) What is the value of a?</u>
we know that
m∠a= -------> by corresponding angles
therefore
<u>the answer part a) is </u>
m∠a=
<u>Part b) What is the value of h?</u>
we know that
m∠h+ ---> by consecutive interior angles (supplementary angles)
m∠h=
m∠h=
therefore
<u>the answer part b) is</u>
m∠h=
<u>Part c) What is the value of b?</u>
we know that
m∠b= -------> by alternate interior angles
therefore
<u>the answer part c) is </u>
m∠b=

the question in English
Mateo will reproduce a photo measuring 5 cm per side on a scale of 3/4
How much will the square side of the copy measure?
Will the size of the copy be larger or smaller than the original?
we know that
the scale factor is equal to
Let
x----------> the original length side
y--------> the copy length side
we have that
substitute the values
therefore
<u>the answer Part a) is </u>
the length side of the copy measure is
Part b)
we know that
the size of the original photo is------>
the size of the copy is------>
so
therefore
<u>the answer part b) is</u>
The size of the copy be smaller than the original
