Mathematics

NNADVOKAT [17]3 years ago
7 0

Answer:

There is no valid value for b

Step-by-step explanation:

We solve the above question using the law of cosines

b² = a² + c² - 2ac × Cos B

B = 42°, a = 6, c = 4

b² = 6² + 4² - 2 × 6 × 4 × Cos 42

b =√6² + 4² - 2 × 6 × 4 × Cos 42

b = √36 + 16 - 48 × Cos 42

Solving the above question, there is no valid value for b

Two sides of a right triangle are 8 and 12. Find the missing side length if 8 and 12 are legs. ​
kipiarov [429]

Answer:

Approximately 14.42

Step-by-step explanation:

All you have to do is use the Pythagorean Theorem! In case you don't remember, it's a² + b² = c², where a and b are legs and c is the hypotenuse.

So...

8² + 12² = c²

64 + 144 = c²

208 = c²

\sqrt{208} = 14.42

A rancher wishes to enclose a rectangular pasture with 320 feet of fencing. the fencing will be used on three sides of the pastu
bulgar [2K]
Let each side perpendicular to the wall be x
The parallel to the wall will be 320-2x
the area will be:
A(x)=x(320-2x)
A(x)=320x-2x^2
This is a quadratic with a =-2 and b=320

Maximum area will occur where x=-b/2a
=-320/(-2*2)
=80 ft
thus the width will be 80 ft and the length will be:
length=320-2*80=160 ft
