Question

these angles of a quadrilateral are equal and The Fourth angle angle measure 135 degree find the measure of the equal angles​

Answer 1

Answer:

75°

Step-by-step explanation:

The sum of all angles in a quadrilateral is 360°.

So 3 angles are equal and one angle is 135°, we can find the measure of the other three angles with this equation:

(360-135)÷3= answer

225÷3

75

so the measure of the remaining 3 angles is 75° each.
