Expert Solution
Step 1

Given:

               sinα=13     ;                  π2<α<π

Hence,

            sin α would be in the second quadrant

            We know,

                                sin α=PH=13

Hence,

           Perpendicular of the triangle = 1 unit;

           Hypotenuse of the triangle= 3 units;

            Base of the triangle = 22 units;

 

 

Step 2

Hence,

               The triangle can be represented as:
