Question

Use the figure below to find the value of x. (x + 20) y (x + 10° (y – 40)

Answer 1

The value of x is 75;

`x=75`

Step-by-step explanation:

From the diagram;

`(x+20)^0+(x+10)^0=180^0`

Reason; supplementary angles.

Solving the equation, we have;

`\begin{gathered} x+x+20+10=180 \\ 2x+30=180 \\ 2x=180-30 \\ 2x=150 \\ x=(150)/(2) \\ x=75 \end{gathered}`

Therefore, the value of x is 75;

`x=75`
