Ross calculated the missing side length of the triangle F.
Solution:
Let us first define the Pythagoras theorem.
Pythagoras theorem:
<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>
So, it is clearly define that Pythagoras theorem is applied for right triangles only.
Right angle is indicated by the symbol "L".
In the given triangles,
E is acute angled triangle.
G is obtuse angled triangle.
H is acute angled triangle.
F is right angled triangle.
Therefore, Pythagoras theorem can be applied only for triangle F.
So Ross calculated the missing side length of the triangle F.
Answer:
adding both equations
4x+9y=5
-4x+7y=11
+ + =+
________
0 +16y=16
y=1
putting the value of y in first eqn
4x+9×1=5
4x=5-9
4x=-4
x=-1
so the x is -1 and y is 1
It would be -3,7! This is because we're reflecting the x-axis not the y-axis
