By pythagorus theorum In triangle ADC
AD²=AB²-BD²
AD²=(6.2)²-(2.7)²
AD=5.5
Again in triangle ADC
AC²=AD²+BC²
AC²=(5.5)²-(2.5)²
AC²=30.25-6.25
AC=4.8 approx..
Answer:
0
Step-by-step explanation:
It’s not going up or down it’s a straight line
So.. checking the picture below
we can say y = y, or just do a substitution and end up with

once you know, how long is "x", then you can simply use the cosine of 72° to get "r"
thus
A ratio compares two quantities.
penguins = 8
whales = 4
8:4 , now simplify
8/4 = 2
4/4 = 1
2:1 is the ratio.
Final answer: 2:1
