Answer 1

Answer:

Hola

Here is your answer mate_______☺️

Step-by-step explanation:

This follows directly from the Quadrilateral Sum Conjecture which says that the sum of angles in any convex quadrilateral is equal to 360 degrees. Since a rectangle has four angles of equal measure, the measure of each must be 360/4, or 90 degrees.
