Question

100 POINTS AND BRAINILY

Answer 1

`\\ \rm\hookrightarrow sinX=(Perpendicular)/(Hypotenuse)=(5)/(13)`

`\\ \rm\hookrightarrow cosX=(Base)/(Hypotenuse)=(12)/(13)`

`\\ \rm\hookrightarrow tanX=(sinX)/(cosX)=(5)/(12)`

Answer 2

Explanation:

In a right-angled triangle, by definition:

sinX = opposite side / hypothesis

= 5/13

tanX = opposity side / adjacent side

= 5/12

cosX = adjacent side / hypothesis

= 12/13
