Question

PLEASEEE HELP
Questions 4 and 5

Answer 1

Answer:

• Given and explained below.

question 4

using sine rule:

$\sf sinx = \frac{opp}{hyp}$

$\sf sinx = \frac{11}{13}$

$\sf x = sin^{-1}(\frac{11}{13} )$

$\sf x = 57.8$

question 5

using cosine rule:

$\sf cosx =\frac{adj}{hyp}$

$\sf cos(31) =\frac{x}{17}$

$\sf cos(31)*17 =x$

$\sf x = 14.6$

Answer 2

$\\ \rm\hookrightarrow sinx=11/13$

$\\ \rm\hookrightarrow sinx=0.8$

$\\ \rm\hookrightarrow x=sin^{-1}(0.8)$

$\\ \rm\hookrightarrow x=53°$

#5

$\\ \rm\hookrightarrow sin31=x/17$

$\\ \rm\hookrightarrow x=sin31(17)$

$\\ \rm\hookrightarrow x=0.5(17)$

$\\ \rm\hookrightarrow x=8.5$
