Question

What is the answer for the question down below

Answer 1

x = 45°

Explanation:

If AC is a supplementary line, then

x + 90° + x = 180°

solution:

2x + 90° = 180° |subtract 90° from both sides

2x = 90° |divide both sides by 2

x = 45°

Answer 2

`\sf \: b) \: {45}^(o)`

Explanation:

Now we have to,

→ find the required value of x.

Forming the equation,

→ x + x + 90° = 180°

Then the value of x will be,

→ x + x + 90° = 180°

→ 2x = 180° - 90°

→ 2x = 90°

→ x = 90° ÷ 2

→ [ x = 45° ]

Hence, the value of x is 45°.
