Question

26.1.2.
. Find the fourth angle of a quadrilateral whose angles are 90°, 45° and 90°

Answer 1

The fourth angle of a quadrilateral with angles 90°, 45°, and 90° is 135°.

Step-by-step explanation:

In a quadrilateral, the sum of all the angles is always equal to 360°.

Given that three of the angles are 90°, 45°, and 90°, we can find the fourth angle by subtracting the sum of the three given angles from 360°.

So, the fourth angle = 360° - (90° + 45° + 90°) = 135°.
