Question

The measures of two adjacent angles of parallelogram are in the ratio 5:4, Find the measures of each angle​

Answer 1

Answer:

5x +4x=180

so 9x=180

x= 20

now 5x= 100

and 4x= 80

so the angles are 100;80

Step-by-step explanation:

adjacent angle sum is 180

Answer 2

Answer:

Ist Angle = 100°

IInd Angle = 80°

Step-by-step explanation:

Sum of Adjacent Angles = 180°

Ratio = 5 : 4

Ist Angle = [ 5/( 5 + 4) ] * 180° = (5/9)*180 = 100°

IInd Angle = [ 4/( 5 + 4) ] * 180° = (4/9)*180 = 80°
