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:
8c + 10
Step-by-step explanation:
Divide 2/2:
6c - 1 + 2c + 11
Then Collect Like Terms:
6c + 2c = 8c
-1 + 11 = 10
Final: 8c + 10
Answer:
$618
Step-by-step explanation:
