$11.5

Step-by-step explanation:

?/15 = 30/100. Now you can simplify the second fraction to- 3/10. Now cross multiply 15 x 3 = 45 now do 45/10 you're answer is $4.5. Don't forget to subtract that from 15. 15 - 4.5 = $11.5.

Mathematics

$\\ \rm\hookrightarrow cosA/2=1/2$

$\\ \rm\hookrightarrow 2cosA=2$

$\\ \rm\hookrightarrow cosA=1$

Now

$\\ \rm\hookrightarrow sinA=\sqrt{1-cos^2A}$

$\\ \rm\hookrightarrow sinA=\sqrt{1-1^2}$

$\\ \rm\hookrightarrow sinA=0$

Here

A=0°
