Explanation of Solution
Given information: An isosceles triangle with two
Formula Used:
1) The sum of angles in a triangle is 1800.
2) The relationship between the legs of right triangle (shown in figure below) a , b and its hypotenuse c is obtained by using Pythagoras theorem.
It can be expressed as,
Calculation:
Here, the two of the angles in the triangle is given as 450. Therefore, the third angle which is opposite to the side of measure
Thus, the given triangle is a right triangle. So, applying Pythagoras theorem gives,
