Question

The supplement of an angle added to the complement of the angle gives 210°.
Find the angle.

Answer 1

Answer:

120degree

Step-by-step explanation:

we know that the sum of coplemebt angle is 90

therefore

90+120

Answer 2

Answer:

30 degree

Step-by-step explanation:

let the angle be x

so, complementary angle will be (90-x) and the supplimentary angle will be (180-x)

now,the sum

(90-x) + (180-x) = 210

90+180-x-x=210

270-2x=210

270-210=2x

60=2x

x = 30° Ans
