C) The 2 triangles are similar , then we can write:
5x/45 = 20/36 . Cross multiplication:
5x*36 = 45*20
180x = 900 and x = 900/180 , x = 5 (and 5x = 25)
d) Remember the proportionality theorem (or Thales')
You can write the following proportion:
GH/HJ = KL/LM
8/6 = 10/x . Cross multiplication:
8x = 60 and x = 60/8 , x = 7.5
Answer:
B = (3, 3)
Step-by-step explanation:
Since the line segment is fifteen units long, from the looks of it, chopping ⅓ of A's side, led to the ordered pair of (3, 3).
I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.
Is there a picture to go along with this? This question is very vague. If you give me more info I might be able to help.
Answer:
r= C over 2π
Step-by-step explanation:
C = 2πr
To solve for r, divide each side by 2π
C/ 2π = 2πr/ 2π
C/ 2π = r
