Alka Tuli and Rajesh Hassija Solutions for Chapter: Properties of Triangles, Exercise 9: HOTS

If the sides of the triangle are extended in an order, show that the sum of the exterior angles so formed is $360°$.

In an isosceles triangle, the measure of one angle is $90°$ and base $=$ altitude $=x \mathrm{m}$.If the length of the hypotenuse is $a\sqrt{2} m$. Find the value of $a$

In the given figure, find the value of $x$. (Without degree symbol)
