Question

If two adjacent angles of a parallelogram ABCD are (5x-10) and (x+10), then find the
ratio of these angles.
(3​

Answer 1

Answer:

7:2 is the ratio

Step-by-step explanation:

As it is given adjacent angles,

(5x-10)+(x+10)=180 [in a parallelogram sum of adjacent angles=180]

6x=180

x=30 degrees

The angles are 5(30)-10,30+10

i.e. 140,40

Ratio is 140:40=7:2

Answer 2

Step-by-step explanation:

The adjacent angles of parallelogram are supplementary

So the sum of adjacent angles = 180°

5x - 10 + x + 10 =180°

6x =180

x =180/6

x =30

5x-10 = 5(30) -10

= 150 -10

=140

x + 10 = 30 +10

=40

The ratio of these angles are given by

140 : 40

70 : 20

7 : 2
