Question

100 POINTS AND BRAINLIST

Answer 1

$\\ \rm\hookrightarrow sin46=\dfrac{29}{c}$

$\\ \rm\hookrightarrow 0.72=29/c$

$\\ \rm\hookrightarrow c=29/7.2$

$\\ \rm\hookrightarrow c\approx 4$

And

$\\ \rm\hookrightarrow cos46=\dfrac{a}{c}=\dfrac{a}{4}$

$\\ \rm\hookrightarrow a=4(0.7)=2.8$

Answer 2

Answer:

A = 44°

a = 28.0

c = 40.3

explanation:

A = 180° - 90° - 46°

A = 44°

using tan rule:

$\sf tan(x)= \dfrac{opposite}{adjacent}$

$\sf tan(46)= \dfrac{29}{a}$

$\sf a= \dfrac{29}{tan(46)}$

$\sf a= 28.0$

using sine rule:

$\sf sin(x)= \dfrac{opposite}{hypotensue}$

$\sf sin(46)= \dfrac{29}{hypotensue}$

$\sf hypotensue= \dfrac{29}{sin(46)}$

$\sf hypotensue= 40.3$
