(sec O - 1)(sec O - 2)
sec O = 1 , 2
O = 45 , 26.6 degrees These are the angles in first quadrant
Answer:
not a right triangle
Step-by-step explanation:
We can use the Pythagorean theorem to see if it is a right triangle
a^2 + b^2 = c^2
15^2 + 12^2 = 21^2
225 + 144 = 441
369 = 441
This is not true so it is not a right triangle
