Explanation

Step 1:

Given data

\theta\text{ = 45}

Step 2:

Write the equations relating polar to rectangular coordinates are

\theta\text{= arc}\tan (\frac{y}{x})\text{ or }\tan (\theta)\text{ = }\frac{y}{x}\text{ and r = }\sqrt[]{x^2+y^2}

Since your polar equation has no "r" we will not need the last equation.

Step 3:

\text{Substitute the value of }\theta\text{ = 45}

Therefore

\begin{gathered} \tan 45\text{ = }\frac{y}{x} \\ \tan \text{ 45 = 1} \\ 1\text{ = }\frac{y}{x} \\ \text{Cross multiply} \\ y\text{ = x} \end{gathered}

Final answer

y = x

Step-by-step explanation:

1 lb ---> 80 cents

5 3/4 lb ---> 5 3/4 * 80 cents

5 \dfrac{3}{4} \times 80 =

= \dfrac{23}{4} \times \dfrac{80}{1}

= \dfrac{23 \times 80}{4 \times 1}
