The sum of two angles of a triangle is equal to its third angle. Determine the measure of the third angle.

Explanation

Let measure of two of its equal angles be x
And, third angle be
Then, x+x= y
But, according to angle sum property of a triangle,
Sum of all angles of a triangle = 180@
So,` x+x+y=180@
=> y@ +y@ = 180@
=> 2y = 180@
Therefore, y = 90@`.
Hence, other angles are `45@`
