Answer: $2061.55\ m$

Step-by-step explanation:

Given

The two communication mask are 2 km apart

Ubi's home is 500 m east of one of the mask

Suppose its distance from the other's is x

From the figure, we can write

$\Rightarrow x^2=2000^2+500^2\\\Rightarrow x^2=4\times 10^6+25\times 10^4\\\Rightarrow x=2061.55\ m\ \text{or}\ 2.061\ km$

The angle is 52 degree.

Step-by-step explanation:

length of of side, L = 8

Hypotenuse, H = 13

According to the trigonometry,

$cos y = \frac{L}{H}\\\\cos y = \frac{8}{13}\\\\cos y = 0.62\\\\y = 52^0$

Question on picture!!!!!!!!

Nat2105 [25]

Answer:

1st option

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use (3, 8 ) , that is x = 3 when y = 8 , then

8 = $\frac{k}{3}$ ( multiply both sides by 3 )

24 = k

y = $\frac{24}{x}$ ← equation of variation
