Question

If two adjacent angles of a parallelogram are in the ratio 4:5, then the measure of the angles are
A. O 720, 1080
B. O 800, 1000
C. O 60°, 1200
D. O 1100 700​

Answer 1

Answer:

option B

Step-by-step explanation:

as the sum of adjacent angles of parallelogram is 180°.

i.e., A + B = 180°

let 4x and 5x be the adjacent angles

4x + 5x = 180

9x = 180

x = 20

then

one angle = 4x = 4×20 =80°

other angle = 5x = 5×20 =100°
