The area of a parallelogram is 26, and the lengths of its sides are 9.3 and 9.8. Determine, to the nearest tenth of a degree, th

Elena L [17]

Answer:

16.6°

Step-by-step explanation:

area = ab sinθ a and b: base and oblique side length θ: angle between

26 = 9.3 x 9.8 sinθ

sinθ = 26 / (9.3 x 9.8) = 0.285276

θ = 16.6

A ship is docked at an island that is 102.5 km south and 31.4 km east of the ship’s

Answer:

$\theta=287^o$

Step-by-step explanation:

<u>Position in the Plane </u>

If we place an object in a plane and mesure its x and y coordinates, we are referencig its position according to the rectangular system. Other popular way to reference positions is in polar form or magnitude-angle form. If we have the rectangular coordinates (x,y), we can easily find the polar coordinates $(r,\theta)$ (and vice-versa). We use the formulas

$r=\sqrt{x^2+y^2}$

$\displaystyle tan\theta=\frac{y}{x}$

We have x=31.4 Km East (a positive coordinate) and y=-102.5 Km South (negative because it's pointing downwards). we need to find the angle respect to the East reference where $\theta=0^o$ . Check the image below for reference.

$\displaystyle tan\theta=\frac{-102.5}{31.4}=-3.264$

$\theta=-73^o$

The angle can be also given as a positive quantity by adding 360^o

$\theta=-73^o+360^o$

$\boxed{\theta=287^o}$

So far, the earliest finds of modern Homo sapiens<span>skeletons come from Africa. They date to nearly 200,000 years ago on that continent. They appear in Southwest Asia around 100,000 years ago and elsewhere in the Old World by 60,000-40,000 years ago.</span>
