If cos(θ) = -4/5, how do I find all the exact values of the other 2 primary trig ratios (sin and tan) and all possible approximate values of θ (to the nearest degree), when 0° ≤ θ ≤ 360°?

go to app and search it okay don't tell me thank you you are always welcome my friend

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
