Find the solutions for a triangle with a = 16, c =12, and B = 63º.

maks197457 [2]

Answer:

b. A = 71.6°; C = 45.40°; b =15.0

Step-by-step explanation:

The missing values can be found with the help of the Law of Cosine and properties of triangles:

Side b (Law of Cosine)

$b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}$

$b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}$

$b \approx 15.022$

Angle A (Law of Cosine)

$\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}$

$\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}$

$\cos A = 0.315$

$A= \cos^{-1} 0.315$

$A \approx 71.639^{\circ}$

Angle C (Sum of internal angles in triangles)

$C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}$

$C = 45.361^{\circ}$

Hence, the right answer is B.

If 3x−y=12, what is the value of 8x/2y?

patriot [66]

Answer:

17.2

Step-by-step explanation:

3x=12+y

x=12+y/3

$8( \frac{12 + y}{3}) \div 2y$

$\frac{96 + 8y}{3} \times \frac{1}{2y}$

$\frac{96 + 8y}{6y}$

(y is divided by y so it no longer exists)

$\frac{96 + 8}{6}$

$\frac{104}{6}$

$17.2$

6 to the power of 8 divided by 6 to the power of 4

tensa zangetsu [6.8K]

Answer:

7.716049382716049e-4‬ or 1,296

Step-by-step explanation:

If 6 is to the power of 8 and my mind is not mistaken. Then it's 6^8=1,679,616 and then divide that by 6 to the power of 4 is 6^4=1,296. In the end with the numbers set. 1,679,616 Divided by 1,296 or 1,296 divided by 1,679,616.
