Answer:
There are 45 stamps from Africa
Step-by-step explanation:
10% of 150 is 15
30% of 150 is 45
15*3 = 45
Answer:
No
Step-by-step explanation:
Pythagorean Theorem is "a^2+b^2=c^2"
Step 1) 1^2+6^2=37
37=c^2
Step 2) The square root of 37 is 6.08
That's not 9
So they don't form a Pythagorean triple
Answer:
Part a) By alternate interior angles
Part b) By vertical angles
Part c) By AAA (Angle-Angle-Angle) Similarity Theorem
Part d) Triangles ABC and CDE are similar
Part e)
or 
Step-by-step explanation:
Part a)
we know that
If AB is parallel to DE
then
m<1=m<4 ------> by alternate interior angles
Part b)
we know that
m<5=m<6 -------> by vertical angles
Part c) we know that
The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal
so
m<1=m<4
m<5=m<6
m<3=m<2
Part d) we know that
If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
therefore
Triangles ABC and CDE are similar
Part e) Find the length side of b
Remember that
If two figures are similar, then the ratio of its corresponding sides is equal
so

substitute the values
