Answer:
it would take 40 pounds of pressure to break the board.
Step-by-step explanation:
Now we plug in the numbers of force and length
Now we multiply both sides by 2.5 to get rid of the fraction.
Now we plug in our variation constant
So we convert the length of 2.5 feet into inches. This is 18 inches. Since there are 12 inches in one foot, we have that 18 inches is equal to 18 divided by 12.
18÷12=1.5
We get that 18 inches is equal to 1.5 feet
we plug L = 1.5 into our inverse variation equation and solve for F.
This simplifies to F = 40

Answer:
Sin A = 0.38462
Step-by-step explanation:
From the trigonometric function,
Sin A = ................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
=
+
= +
= 576 + 100
= 676
Hyp =
= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A =
Sin A = 0.38462
