Answer:
The value of x is 75;
[tex]x=75[/tex]
Explanation:
From the diagram;
[tex](x+20)^0+(x+10)^0=180^0[/tex]
Reason; supplementary angles.
Solving the equation, we have;
[tex]\begin{gathered} x+x+20+10=180 \\ 2x+30=180 \\ 2x=180-30 \\ 2x=150 \\ x=\frac{150}{2} \\ x=75 \end{gathered}[/tex]
Therefore, the value of x is 75;
[tex]x=75[/tex]
