Answer 1

Answer: I think x = -4

Step-by-step explanation: I used a calculator.

Answer 2

x = -4°

Explanation:

We know that,

→ Sum of angles of straight line is 180°.

Now we have to,

→ Find the required value of x.

Forming the equation,

→ (54°) + (7x + 154°) = 180°

Then the value of x will be,

→ 7x + 154° + 54° = 180°

→ 7x + 208° = 180°

→ 7x = 180° - 208°

→ 7x = -28°

→ x = -28° ÷ 7

→ [ x = -4° ]

Hence, the value of x is -4°.
