Question

14. Two adjacent angles on a straight line are in ratio 3:7. Find the measure of each of these angles.​

Answer 1

Answer:

Consider the two adjacent angles as 5x and 4x

We know that the two adjacent angles form a linear pair

So it can be written as

5x+4x=180

o

⇒9x=180

o

x=20

o

substituting the value of x in two adjacent angles

5x=5(20)=100

o

4x=4(20)=80

o

Answer 2

Answer:

3:7

3/10×180

=54

7/10×180

=126

54:126
