Question
Find the value of x.
Hint:
- The angle made by a straight line is called a straight angle.
- Measure of straight angle is 180o.
The correct answer is: 44
Step by step explanation:
- Given :𝑚∠AOB = (x + 4)°
𝑚∠BOC = 3x°.
- Step 1 : From the figure it is clear that,
∠POS is straight angle hence ∠AOC = 180o.
and
∠AOC = ∠AOB + ∠BOC
- Step 2 : Put values of ∠AOC and ∠BOC
∠AOC = ∠AOB + ∠BOC
180 = (x + 4) + 3x
180 = 3x + x + 4
180 = 4x + 4
4x = 180 - 4
4x = 176
x = 
x = 44
- Final Answer:
Hence, the value of x is 44.
- Given :𝑚∠AOB = (x + 4)°
