The sum of two opposite angles of a quadrilateral is 280°. The other two angles are equal. Find the measure of the equal angles. (Please)

40° each

Step-by-step explanation:

The interior angles of a quadrilateral add up to 360°.

360° - 280° = 80°/2 = 40°

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 "
