Question

3. The two angles measuring (30° - a) and ( 1250 - 2a)
are supplementary to each other. Find the value of a.​

Answer 1

Step-by-step explanation:

we know that supplementary angle is 180'

than (30'-a) +(1250'+2a)_- 180'

30' - a + 1250' + 2a-_180'

1280' + a_- 180'

a-_ 180' -1280'

a_-1100

Answer 2

Answer:

may be the answer is 1100/3

I am not sure

Step-by-step explanation:

(30'-a)+(1250-2a) = 180

30' +1250-a-2a = 180

1280-3a =180

1280-180

1100=3a

1100/3 = a
