Question

Please help geometry Trig I need 12 through 15 please asap

Answer 1

`DC=30.430\approx30.4`

12) In this triangle, we need to find the projection DC. Let's start out finding the height, by using a trig ratio (sine):

`\begin{gathered} \sin(54)=(h)/(20) \\ h=20*\sin(54) \\ h=BD=16.18\approx16 \end{gathered}`

12.3) Based on another trig ratio we can write out the following formula:

`\begin{gathered} \tan(28)=(16.180)/(DC) \\ DC=(16.180)/(\tan(28)) \\ DC=30.430 \end{gathered}`
