Answer: 8 weeks

explanation: 125 + 15x = 245

You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.

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
