DedPeter [7]

Answer:

Step-by-step explanation:

L and W are length and width, respectively.

W = 3¼ = 13/4

Area = LW = 27⅝ = 221/8 m²

L = area/W = (221/8)/(13/4) = (221/8)(4/13) + 221/26 = 17/2 = 8½ m

Show that the cosine law simplifies to the Pythagorean theorem when the contained angle between the two known sides is 90°.

mixas84 [53]

Answer:

See Below.

Step-by-step explanation:

We want to show that the Law of Cosines simplifies to the Pythagorean Theorem when the contained angle between the two known sides is 90°.

The Law of Cosines is given by:

$c^2=a^2+b^2-2ab\cos(C)$

Where <em>a </em>and <em>b</em> are the two known sides, and C is the angle between them.

If C is 90° then we will have:

$c^2=a^2+b^2-2ab\cos(90 ^\circ)$

Recall that the cos(90°)=0. Hence:

$c^2=a^2+b^2-2ab(0)$

Simplify:

$c^2=a^2+b^2$

So, we acquire the Pythagorean Theorem as desired.
