Answer:
a.12/13
Step-by-step explanation:
- FORMULA: sine of an angle in a triangle is given by,

- here, in the given triangle PQR, for angle 'p'
opposite side= QR
adjacent side= PQ
hypotenuse=PR
- Therefore, sine of angle p=

- Thus, by using the above given formula, the sine of angle p in the triangle PQR is 12/13.
- hence, the trigonometric formulas as mentioned above should be remembered for sure to solve these type of problems
