The triangle with sides 40m, 50m, 60m is not a right angled triangle .
What is Pythagoras' theorem?Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
Pythagoras' theorem :
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
According to the question
Sides of triangle are 40m, 50m, 60m
As hypotenuses is the largest side
Applying Pythagoras' theorem
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
[tex]60 ^{2} = 40^{2} + 50^{2}[/tex]
3600 ≠ 1600 + 2500
3600 ≠ 4100
Hence, The triangle with sides 40m, 50m, 60m is not a right angled triangle ,

The lines represented by the equations 20y-24x=-20y and 5y-6x=-5 are
a) perpendicular
b) the same line
c) neither parallel nor perpendicular
d) parallel
Answers
Answer:don’t listen to the other guy he’s wrong. The answer is the same line.
Step-by-step explanation:
20y-24x=-20 add 24x to both sides
20y=24x-20
Divide 20 to all
New equation is
Y=5/6x-1
Now let’s solve for 5y-6x=-5
Add 6x to both sides
5y=6x-5
Divide 5 to all
The new equation is
Y=6/5x-1
As you see they have the same equation so the answer is that the lines are the same :) have a good day guys hope this helped <3

Write the new equation for g.
G=
Answers
Answer:
[tex]g(x) = 4^{x-1} + 3[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4^x[/tex]
[tex]g(x) = f(x-1) + 3[/tex]
Required
Determine g(x)
First, we need to calculate f(x-1)
Given that:
[tex]f(x) = 4^x[/tex]
Subtract 1 from x
[tex]f(x-1) = 4^{x-1}[/tex]
Add 3 to both sides
[tex]f(x-1) + 3 = 4^{x-1} + 3[/tex]
Recall that:
[tex]g(x) = f(x-1) + 3[/tex]
This implies that:
[tex]g(x) = 4^{x-1} + 3[/tex]
