Step-by-step explanation:
How to find x:
tan(45)= 5/x
x = 5/tan(45) [Find on calculator]
How to find y:
Pythagoras' theorem:
a² + b² = c²
5² + x² [value found in first part] = y²
Square root the sum of 5² + x² and the y²
The answer of the square root of the sum is the value of y

We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant. hence the answer is 2.
