Answer:
X= 10
Step-by-step explanation:
let the vertex of angle 17° named A
then the other two B and C
then by using trigonometry:
sin(A) = opposite side divided by hypotenuse
opposite side is. X
Wich makes Sin(A) = X/47
then by crossing X= sin(A) × 47 = 13.74147
rounding to the nearest tenth: X= 10
Answer:
10:40
Step-by-step explanation:
As the left number increases by 1, the right number increases by 4. So as you can see, the left numbers go 3-4-5 while the right numbers go 12-16-20. So the answer is 10:40 because 10x4=40.
