Answer:

hope this will help you (•‿•)

Explanation:


for \: 1st \: qn \: \\ let \: the \: angle \: be \gamma \\ \cos( \beta ) = (b)/(p) \\ \cos( \beta ) = (16)/(34) \\ \beta = \cos {}^( - 1) ( { 0.470}^( ) ) \\ \beta = 61.965 \\ for \: 2nd \: qn \\ let \: the \: angle \: be \: \alpha \\ \tan( \alpha ) = (p)/(b) \\ \tan( \alpha ) = (20)/(15) \\ \alpha = \tan {}^( - 1) (1.33) \\ \alpha = 53.061
