Question

The measure of two adjecent angles at parellalogram are 4:5 find the measure of each of the angle of parellalogram​

Answer 1

Answer:

80°, 100°, 80°, 100°.

Step-by-step explanation:

The sum of all angle of parallelogram=360°

Let the ratio be x.

4x+5x+4x+5x=360°

18x=360°

x=360°\18

x=20°

so,

4x=4×20°=80°

5x=5×20°=100°

4x=4×20°=80°

5x=5×20°=100°
