Answer:

Step-by-step explanation:
We have a right angled triangle given.
At first, let's note that, sin θ = oppposite side of the triangle / hypotenuse of the triangle.
Now, in the given triangle, from the view of ∠θ,
- Opposite side of the triangle = 8
- Hypotenuse = 10
Then,


13 x 6 = 78 you cant multiply anymore so that's how many times it can go in 80.
3p-(-20)=50
3p+20=50 subtract 20 from both sides
3p=30 divide both sides by 3
p=10
