This is my next Trigonometry question I am needed help on- I just want to be sure I've got it right, or if not, then the steps I
Reptile [31]
\bf cos(\theta)=\cfrac{3}{5}\cfrac{\leftarrow adjacent=a}{\leftarrow hypotenuse=c}
\\\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-a^2}=b\implies \pm\sqrt{5^2-3^2}=b
\\\\\\
\pm\sqrt{16}=b\implies \pm4=b

so, plus or minus?  well, the angle is in the 1st quadrant, and on that quadrant, both cosine and sine are positive, so 4 = b

\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(\theta)=\cfrac{4}{3}

Use a table of signs to solve the inequality
bulgar [2K]

The interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

The inequality given in the problem is,

4x + \dfrac{5}{9} - 3x \geq 0

Simplify the equation first by adding the same terms,

4x + \dfrac{5}{9} - 3x \geq 0\\4x - 3x+ \dfrac{5}{9}  \geq 0\\x+ \dfrac{5}{9}  \geq 0\\x\geq-\dfrac{5}{9}

Now in this case, if the value x is ranges from -5/9 to infinity.

Thus, the interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.
