Answer:
Step-by-step explanation:
The triangle is right isosceles.
It is right as the side is the diameter of the circle.
It is isosceles as two sides marked as equal.
Acute angles are same and equal to:
Correct option is 45°
<M=90°[inscribed angle on diameter is 90°]
<N=<L=[base angle of isosceles triangle]
now
<M+<l+<N=180°[sum of interior angle of traingle]
[2x-5]×2=180-90
4x-10=90
x=100/4=25
x=25
