Question

If ratio of two angles of a linear pair is 7:5find the angle

Answer 1

Step-by-step explanation:

one angel is 7x

another is 5x

7x + 5x = 180

12x = 180

x = 180/12

x = 15

Answer 2

Answer:

Let the 2 angles be 7x and 5x respectively.

7x+5x=180(linear pairs add up to 180)

12x=180

x=180/12

x=15

Therefore 7x=7(15)=105 degrees

and 5x=5(15)=75 degrees

Therefore the angles are 105degrees and 75 degrees .
