To prove a similarity of a triangle, we use angles or sides.
In this case we use angles to prove
∠ACB = ∠AED (Corresponding ∠s)
∠AED = ∠FDE (Alternate ∠s)
∠ABC = ∠ADE (Corresponding ∠s)
∠ADE = ∠FED (Alternate ∠s)
∠BAC = ∠EFD (sum of ∠s in a triangle)
Now we know the similarity in the triangles.
But it is necessary to write the similar triangle according to how the question ask.
The question asks " ∆ABC is similar to ∆____. " So we find ∠ABC in the prove.
∠ABC corressponds to ∠FED as stated above.
∴ ∆ABC is similar to ∆FED
Similarly, if the question asks " ∆ACB is similar to ∆____. "
We answer as ∆ACB is similar to ∆FDE.
Answer is ∆ABC is similar to ∆FED.
5u > 64 - 14
5u > 50
u > 10
Answer: 8(x+5) 8x + 40
40 + 8x
Step-by-step explanation:
Distribute the 8 by multiplying by each value inside the parentheses.
Commutative property in addition and multiplication allows the terms to be in reversed order.
Answer:
1 A= 3 cm
2 C= 37/99
Step-by-step explanation:
Volume is l * w * h
or s³ for cubes
∛27= 3
3/7= 0.43
3/70= 0.04
37/99= 0.3737373737 etc.
37/100= 0.37
