Please help me with this trigonometry question:
zzz [600]

Answer:

The distance from A to B is 736.2 to the nearest tenth foot

Step-by-step explanation:

In ΔCAB

∵ m∠CAD = 30° ⇒ exterior angle of Δ at vertex A

∴ m∠CAD = m∠ACB + m∠ABC

∵ m∠ABC = 20°

∴ m∠ACB = 30° - 20° = 10°

We will use the sin rule to find the distance AB

∵ \frac{sin20}{1450}=\frac{sin10}{AB}

∴ AB=\frac{1450(sin10)}{sin20}=736.1842936 ≅ 736.2 to the nearest tenth foot

If q, s, and t are all different numbers, is q &lt; s &lt; t ?
inessss [21]
It very well could be, but not necessarily. What if q = 10, s = 8, and t = 6?

The statement is that q is less than s, and s is less than t (which therefore also means q is less than t).

However, when we substitute (replace) all the letters with the values we assigned them, we can find that the expression becomes:

10 < 8 < 6

This clearly isn’t right, as 10 is the greatest number there, and 8 is definitely less than 10 and greater than 6.
