Answer:

x = 20.6°

using cosine rule:

[tex]\sf cos(x)= \dfrac{adjacent}{hypotensue}[/tex]

using the formula:

[tex]\sf cos(61)= \dfrac{10}{x}[/tex]

[tex]\sf x= \dfrac{10}{cos(61)}[/tex]

[tex]\sf x= 20.6[/tex]

[tex]\\ \rm\hookrightarrow cos61=\dfrac{10}{x}[/tex]

[tex]\\ \rm\hookrightarrow x=10/cos61[/tex]

[tex]\\ \rm\hookrightarrow x=10/0.5[/tex]

[tex]\\ \rm\hookrightarrow x=20[/tex]
