Point and line are geometric terms for the Eiffel Tower
By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are
sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1
So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .
So the correct options are
b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1
Answer:
13
Step-by-step explanation:
You are not going to be able to find a numerical value of this triangle because you do not know the type of triangle or the other side length. You can represent the perimeter using algebra though.
To find the perimeter you add the lengths of all 3 sides.
To show this as an algebraic expression, you would put 1 dm + 3 dm + x.
This will simplify to x + 4 dm, where x is the length of the missing side (in decimeter).
