To find:
Answer to Problem 25CUR
Explanation of Solution
Given:
The diagram:
Concept Used:
Theorem 5-15: In right triangle, the midpoint of the hypotenuse is equidistant from the three vertices.
Theorem 4-1: Opposite angles of equal sides in triangle are equal.
Theorem 3-11: The addition of all angles of a triangle is 180.
Consider the figure shown below:
Consider the right triangle
Now,
So, by theorem 5-15, the midpoint Y of the hypotenuse
Thus,
Now, consider the triangle
That is,
Now it is given that
Also,
Since,
So,
Now consider,
Apply theorem 3-11 on triangle
Now, it is given that
So
Now, apply theorem 3-11 on triangle
Now consider,
