Mathematics

Based on the angle measures given, which triangle is not acute?


ANSWER

$$90^\circ,\, 45^\circ,\, 45^\circ$$


SOLUTION
For acute angles triangle all the three angles must be less than $${ 90 }^{ \circ  }$$.
In option $$D$$ one of the angle is $${ 90 }^{ \circ  }$$ , so it is not acute angles triangle.
