Question

the sum of the two angles is 8 and their difference is 20 find all the angles​

Answer 1

Answer:

a+b=8

a-b=20

add both the equations

2a=28

a=14

Substituting a in 1st equation

14+b=8

b=-6

Therefore the angles (a,b) are (14,-6)

Hope the answer helps you thank you

Answer 2

Answer:

Let the two angles be 'a' and 'b'

Sum:

a+b=8

Difference:

a-b=20

a=20+b

20+b+b=8

2b=(-12)

b=(-6)°

a=20+b=20+(-6)=14
