Step 1.3.1

Factor $4$ out of $180$ .

$\frac{17}{4} \cdot (4 (45))$

Step 1.3.2

Cancel the common factor.

$\frac{17}{4} \cdot (4 \cdot 45)$

Step 1.3.3

Rewrite the expression.

$17 \cdot 45$

Step 1.4

Multiply $17$ by $45$ .

$765$

Step 1.5

Convert to a decimal.

$765 °$

Step 2

For angles greater than $360 °$ , subtract $360 °$ from the angle until the angle is less than $360 °$ .

$45$

Step 3

The angle is in the first quadrant.

Quadrant $1$
