PLEASEEE HELP
Questions 4 and 5

Answer 1

`\\ \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`

Answer 2

• Given and explained below.

question 4

using sine rule:

`\sf sinx = (opp)/(hyp)`

`\sf sinx = (11)/(13)`

`\sf x = sin^(-1)((11)/(13) )`

`\sf x = 57.8`

question 5

using cosine rule:

`\sf cosx =(adj)/(hyp)`

`\sf cos(31) =(x)/(17)`

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

`\sf x = 14.6`
