Arte-miy333 [17]

The distance of the cell phone from the western tower is 27.47 miles and from the eastern tower is 1.76 miles

Explanation:

The sketch is attached for the reference.

tan (10) = $\frac{NE}{WE}$

$0.176 = \frac{NE}{10} \\\\NE = 1.76$

tan (70) = $\frac{NW}{WE} \\\\$

$2.747 = \frac{NW}{10} \\\\NW = 27.47$

Therefore, the distance of the cell phone from the western tower is 27.47 miles and from the eastern tower is 1.76 miles

what is the order from least to greatest - 4 with the exponent of 3, square root of 40, square root of 13, square root of 7, , 1

LuckyWell [14K]

Answer: $-4^{3}$ , 14/9 , $\sqrt{7}$ , $\sqrt{13}$ , $\sqrt{40}$

Step-by-step explanation:

$-4^{3}$ = - 64

$\sqrt{40}$ = 6.32455532

$\sqrt{13}$ = 3.605551275

$\sqrt{7}$ = 2.645751311

14/9 = 1.555555556

Arranging from least to greatest , we have :

$-4^{3}$ , 14/9 , $\sqrt{7}$ , $\sqrt{13}$ , $\sqrt{40}$
