Question

The angles of a quadrilateral are (5x)^o, (3x + 10)^o, (6x – 20)^o and (x + 25)^o. Now, the measure of each angle of the quadrilateral will be

• A. 115^o, 79^o, 118^o, 48^o
• B. 75^o, 89^o, 128^o, 68^o
• C. 100^o, 79^o, 118^o, 63^o
• D. 110^o, 84^o, 106^o, 60^o

Answer 1

The correct option is A

115^o, 79^o, 118^o, 48^o

Sum of the angles of a quadrilateral is 360^o.

(5x)^o + (3x + 10)^o + (6x – 20)^o + (x + 25)^o = 360^o

x = 23^o.

The angles are 115^o, 79^o, 118^o and 63^o.
