There are 3280 feet 10.079 inches in one kilometer
Answer:
<u>x = 466.7 feet</u>
Step-by-step explanation:
Finding the top angle of the triangle :
- They are complementary
- 90° - 31°
- 59°
Take the tan value of this angle to find y :
- tan 59° = 400/y
- 1.66427948 =400/y
- y = 400 / 1.66427948
- y = 240.344248
Using Pythagorean Theorem to find x :
- y² + 400² = x²
- x = √(240.344248)² + 160000
- x = √57765.3575 + 160000
- x = √217765.357
- <u>x = 466.7 feet</u> (nearest tenth)
(-79.54) / (-9.7) = <span>8.2
Steps:

<span><span>Conversion: 79.54 = <span>7954/100</span> = <span>3977/50
</span></span><span>Unary minus: -79.54 = -<span>3977/50</span></span><span>
Conversion: 9.7 = <span>97/10</span></span><span>
Unary minus: -9.7 = -<span>97/10
</span></span><span>Divide: -<span>3977/50</span> / (-<span>9710</span>) = <span>-397750</span> · <span>10-97</span> = <span>-3977 · (-10)50 · 97</span> = <span>397704850</span> = <span>415
