Subtract the 5cos(x)=>3sin(x)=-5cos(x) Divide by -5cos(x)=> (-3/5)tan(x)=1 Multiply by -5/3=>tan(x)=-5/3=>x=arctan(-5/3)

3 sin x + 5 cos x = 0
3 sin x = - 5 cos x  /: cos x ( divide both sides by cos x )
3 sin x / cos x = - 5
3 tan x = - 5
tan x = -5/3
x = arc tan (-5/3)
x ≈ - 59.036°

Find the measure of 0. Round answer to the nearest tenth. Pleas help
DENIUS [597]

Answer:

\theta=36.43^{\circ}

Step-by-step explanation:

Given that,

Base = 42

Perpendicular height = 31

We need to find the value of \theta. It can be calculated using trigonometry as follows :

\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})

Put all the values,

\theta=\tan^{-1}(\dfrac{31}{42})\\\\\theta=36.43^{\circ}

So, the value of \theta=36.43^{\circ}.
