For a triangle to be obtuse only one of the angles must br shown to be obtuse. (in fact only one of the angles can possibly be obtuse) but for a triangle to be acute all three angles must be shown to be acute. explain why determining one acute angle with the pythagorean inequalities theorem shows that the triangle is acute

The explanation is given below.

Step-by-step explanation:

Given for a triangle to be obtuse only one of the angles must be shown to be obtuse but for a triangle to be acute all three angles must be shown to be acute.

According to Pythagoras theorem for a right angled triangle which has one angle of 90° rest of two are acute.

Hence, by Pythagorean inequality

which gives the triangle is acute.

Hence, one acute angle with the Pythagorean inequalities theorem shows that the triangle is acute.

b is the answer that makes most sense

step-by-step explanation:

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
