Hey! Apologies that I can’t make this look nice because I’m on mobile.
To simplify this, we can multiply the denominator by its conjugate. For a imaginary function (a+bi), its conjugate would be (a-bi), so we can apply that here to multiply both sides by (2-i)/(2-i). This works because it simplifies to one. Then, we have our fraction as 4*(2-i)/((2-i)(2+i))=(8-4i)/(4-i^2)=(8-4i)/5
Feel free to ask further questions, and have a great rest of your day!
Answer:
<h3>x = 22.54</h3>
Step-by-step explanation:
Tangent θ = Opposite / Adjacent
tan(29) = 20/x
Cross multiply.
x = 20 / (tan(29))
x = 22.544284
