Question

if two adjacent angles of a parallelogram are X and (X+30) then X=​

Answer 1

Answer:

x=75

Step-by-step explanation:

x+x+30=180

2x+30=180

2x=180-30

2x=150

x=150/2

x=75

Answer 2

If two adjacent angles of a parallelogram are X and X + 30° then X is equal to 75°

Given :

Two adjacent angles of a parallelogram are X and X + 30°

To find :

The value of X

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that two adjacent angles of a parallelogram are X and X + 30°

Step 2 of 2 :

Find the value of X

We know that in a parallelogram the adjacent angles are supplementary

Thus we get

X + X + 30° = 180°

⇒ 2X + 30° = 180°

⇒ 2X = 180° - 30°

⇒ 2X = 150°

⇒ X = 75°

Hence the required value of X = 75°
