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

<u>Explanation:</u>

<u></u>

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

List two sets of possible side lengths for two triangles, one set that forms a triangle and one set that does not.

Nataliya [291]

In any triangle, the sum of lengths of any two sides must be greater than the third side.

(1) If we chose three side lengths to be 5 cm, 7 cm and 10 cm. Let's do the check:
5+ 7 = 12 > 10
5+10 = 15 > 7
7 + 10 = 17 > 5
The sum of any two sides is greater than the third, therefore, these three side lengths can form a triangle.

(2) If we chose three side lengths to be 3 cm, 4 cm and 8 cm.Let's do the check:
3 + 4 = 7 which is not greater than 8
The condition is not fulfilled, therefore, these three side lengths cannot form a triangle.

Answer:

3 / 512

Step-by-step explanation:

If you want to simplify further, reduce the exponents:

2²/2¹⁰ + 2²/2¹¹

1/2⁸ + 1/2⁹

Find the common denominator and add.

2/2⁹ + 1/2⁹
