Answer:

437.3 ft

Step-by-step explanation:

By sine rule:

$\frac{x}{ \sin(90 - 29) \degree} = \frac{500}{ \sin \: 90 \degree} \\ \\ \frac{x}{ \sin 61 \degree} = \frac{500}{1} \\ \\ x = 500\sin 61 \degree \\ \\ x = 500 \times 0.8746197071 \\ \\ x = 437.309854 \\ \\ x = 437.3 \: ft$

Belinda’s mother took the family out to dinner. The food bill came to $72.00. The sales tax is 6% of the cost of food. As a tip,

makkiz [27]

To calculate final cost you need to add tax and tip. Because you tip on the food bill without tax, you just add these two.

72 * 0.2 = 14.4 -> tip
72 * 0.06 = 4.32 -> tax

72 + 14.4 + 4.32 = 90.72

So the total cost was $90.72

You can find that faster:

72 * 1.26 = 90.72
