The picture is a bit blurry. Mind sending it again?
What lesson are you working on ? because there are different formulas to find the solutions for a triangle
For the first question the answer is 1/13. then for the second it is 1/2 and for the third it is 3/10.
Since Seema runs 5 more miles than Padma, we could find how long Padma runs by subtracting 5 miles from the amount of miles that Seema runs. If P is equal to the distance that Padma runs, our equation is:
P = 17-5 = 12 miles.
