Question

What is the value of x? 12 25 38 52

Answer 1

2x +2 + 5x+3 = 180

7x +5 = 180

7x = 175

x = 175 /7 = 25

x = 25

Answer 2

Answer:

Option B is correct that is value of x is 5.

Step-by-step explanation:

Given: ∠ACE = ( 2x + 2 )°   and ∠BCE = ( 5x + 3 )°

To find: Value of x.

Given Angles are pair of linear angles means they together form a straight line.

Thus, ∠ACE + ∠BCE = 180°

         ( 2x + 2 ) + ( 5x + 3 ) = 180

          2x + 2 + 5x + 3 = 180

          7x + 5 = 180

         7x = 180 - 5

          7x = 175

            x = 25

Therefore, Option B is correct that is value of x is 5.
