Q. A triangle has angle measurements of 133∘, 1∘, and 46∘. What kind of triangle is it?Choices:(A) acute(B) right(C) obtuse
Calculate sum of angles: Calculate the sum of the given angles: 133°+1°+46°=180°.
Confirm triangle: Since the sum of the angles is 180∘, it confirms the figure is a triangle.
Identify triangle type: Identify the type of triangle based on the largest angle. The largest angle here is 133∘, which is greater than 90∘ but less than 180∘.
Determine obtuse triangle: Since one angle is greater than 90∘, the triangle is an obtuse triangle.
