We have:
and Quadrant II (x < 0, y > 0)
Therefore y = 5 and r = 6. Calculate x:
Sunstitute to the formula of tan:
Answer: d.
C. greater than 11 and at most 23
you can find this by subtracting the two smaller sides to find the smallest side possible for the 3rd side 17-6=11
to find the largest side possible you can add the to side 17+6=23
