I need this question answered plz help.

Answer 1

Answer:

a.12/13

Step-by-step explanation:

• FORMULA: sine of an angle in a triangle is given by, $\frac{opposite side's length}{length of the hypotenuse}$

• here, in the given triangle PQR, for angle 'p'

opposite side= QR

adjacent side= PQ

hypotenuse=PR

• Therefore, sine of angle p= $\frac{QR length}{PR length} = \frac{12}{13}$

• 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
