Solve cos^2 (B) + 3cos(B) + 2 = 0 for<br> B, 0 < B < 360<br><br> Please help

ANEK [815]

Step-by-step explanation:

$\cos {}^{2} (b) + 3 \cos(b) + 2 = 0$

$( \cos(b) + 2)( \cos(b) + 1) = 0$

$\cos(b) = - 2$

Cosine have a range of [-1,1] so b is undefined for the first factor

$\cos(b) = - 1$

$b = 180$

Pls help me what do the letters stand for

kozerog [31]

Answer:

One possibility is:

S = 6

M = 4

U = 5

T = 1

H = 3

I = 0

N = 9

K = 2

Step-by-step explanation:

If we replace the letters that are being added with:

S = 6

M = 4

U = 5

we have:

$6546\\+\\ 6546\\---\\13092$

where T=1, H=3, I=0, N=9, K=2
