Question

100 POINTS AND BRAINLY

Answer 1

$\\ \rm\hookrightarrow cos61=\dfrac{10}{x}$

$\\ \rm\hookrightarrow x=10/cos61$

$\\ \rm\hookrightarrow x=10/0.5$

$\\ \rm\hookrightarrow x=20$

Answer 2

Answer:

x = 20.6°

using cosine rule:

$\sf cos(x)= \dfrac{adjacent}{hypotensue}$

using the formula:

$\sf cos(61)= \dfrac{10}{x}$

$\sf x= \dfrac{10}{cos(61)}$

$\sf x= 20.6$
