Question

If (30+x)° is supplement of 40°, then value of x is:​

Answer 1

Step-by-step explanation:

supplement means sum of the given numbers=180°

according to the given question,

30+x+40=180

x+70. =180

x=180-7

therefore, x=110°

Answer 2

Solution :-

We know that,

• When two angles are supplementry their sum is equal to 180° .

So, given that,

→ (30 + x)° = supplement of 40°

→ 30° + x° = 180° - 40°

→ 30° + x° = 140°

→ x° = 140° - 30°

→ x° = 110° (Ans.)

Hence , x is equal to 110° .
