The angles of cyclic quadrilaterals ABCD are: A = (6x+10), B=(5x)°, C = (x+y)° and D=(3y-10)°. The value of x and y is:
A. x=20° and y = 10°
B. x=20° and y = 30°
C. x=44° and y=15°
D. x=15° and y=15°
Answer:B
The angles of cyclic quadrilaterals ABCD are: A = (6x+10), B=(5x)°, C = (x+y)° and D=(3y-10)°. The value of x and y is:
A. x=20° and y = 10° B. x=20° and y = 30° C. x=44° and y=15° D. x=15° and y=15°
Explanation: We know, in cyclic quadrilaterals, the sum of the opposite angles are 180°.
