....2.
. Find the fourth angle of a quadrilateral whose angles are 90°, 45° and 90-

Answer 1

The fourth angle of a quadrilateral can be found by subtracting the sum of the given angles from 360°.

Step-by-step explanation:

A quadrilateral is a polygon with four sides. The sum of the interior angles of any quadrilateral is always 360 degrees. In this case, the given angles are 90°, 45°, and 90-. To find the fourth angle, we can subtract the sum of the three given angles from 360°.

90° + 45° + 90- = <<90+45+90*-360=315>>315°

Now, subtract 315° from 360° to find the fourth angle: 360° - 315° = <<360-315=45>>45°.
