Answer: x° = 20

Steps:
100 + x + 3x = 180
x + 3x = 80
4x = 80
x = 80/4
x = 20

Check:
100 + x + 3x = 180
100 + 20 + 3(20) = 180
100 + 20 + 60 = 180
180 = 180 ✅

How do i solve this question
frozen [14]
\bf \begin{cases}&#10;h(x)=(f\circ g)(x)\\&#10;h(x)=\sqrt{x+5}\\&#10;f(x)=\sqrt{x+2}&#10;\end{cases}\\\\&#10;-------------------------------\\\\&#10;(f\circ g)(x)\implies f[\ g(x)\ ]\implies f[\ g(x)\ ]=\sqrt{g(x)+2}\qquad thus&#10;\\\\\\&#10;\sqrt{g(x)+2}=(f\circ g)(x)=h(x)=\sqrt{x+5}\qquad therefore&#10;\\\\\\&#10;\sqrt{g(x)+2}=\sqrt{x+5}\impliedby \textit{squaring both sides}\\\\\\&#10;g(x)+2=x+5\implies g(x)=x+5-2\implies \boxed{g(x)=x+3}
