Then;
Let f be the hypotenuse of the right triangle with sides 2,(x+3), be f.
Then;
We apply Pythagoras Theorem to the bigger right triangle to get;
We are dealing with length.
QUESTION 8.
We apply the leg theorem to obtain;
We discard the negative value;
QUESTION 9;
We apply the leg theorem again;
Factor;
Discard the negative value;
QUESTION 10
According to the leg theorem;
The length of a leg of a right triangle is the geometric mean of the lengths of the hypotenuse and the portion of the hypotenuse adjacent to that leg.
We apply the leg theorem to get;
units.
