Question

Three angles of quadrilateral are equal. Fourtj angle is 150°. Find equal angles

Answer 1

Answer:

we know that the sum of interior angle in a quadrilateral is 360°. hence the measure of each equal angle in the quadrilateral is 70°. hence verified. thus the angles in the quadrilateral are 70°,70°,70° and 150°.

Answer 2

Step-by-step explanation:

Let the angels be X,X,X

We know the sum of all angles of a quadrilateral is 360 degree ( sum angle property )

thus

X + X + X + 150 = 360

3X + 150 = 360

3X = 210

X = 70

the equal angels 70,70,70
