First you check for Pythagoras' Theorem.
Is 8.6² = 8.1² + 2.6² ?
8.1² + 2.6² = 65.61 + 6.76 = 72.37
8.6² = 73.96
8.1² + 2.6² ≠ 8.6²
Since Pythagoras' Theorem is not satisfied it is not a right angled triangle.
The longest side is 8.6, let's find the angle facing the longest side 8.6.
By cosine formula CosA = (b² + c² - a²) / (2bc)
CosA = (2.6² + 8.1² - 8.6²) / (2*2.6*8.1) = -1.59/42.12 = -0.0377
A = Cos inverse (-0.0377) = 92.1 degrees
So there is an angle is greater than 90 degrees.
Answer:
The question is incorrect as it lacks the "x" component. Function f(x) cannot be stated without the x, elseways it couldn't be called "f(x)"
Answer:
Step-by-step explanation:
Given the scale factor 1 : 4 , then
the area factor = 1² : 4² = 1 : 16
That is area of polygon H is area of polygon G
t = 
multiply both sides by 6rt
6crt = 1 ( divide both sides by 6ct to obtain r )
t =
