Answer:

Step-by-step explanation:

Cos(Q) = adjacent to Q/Hypotenuse

adjacent = 15

Hypotenuse = 17.7

Cos(Q) = 15/17.7

Cos(Q) = 0.8475

The answer is C.

D is impossible. The cos of any angle can never be more than 1.

B is Tan(Q). They are not the same.

A is Sin(Q)

Answer:

y = 1/2x - 6

Step-by-step explanation:

y2 - y1 / x2 - x1

-2 - (-5) / 8 - 2

3 / 6

= 1/2

y = 1/2x + b

-5 = 1/2(2) + b

-5 = 1 + b

-6 = b

Please help me. I suck at math

Answer:

Answer is ...Obtuse

Step-by-step explanation:

$\frac{m$

$\frac{5x + 4}{2} = \frac{3}{2} x + 21$

$\frac{5x + 4}{2} = \frac{3x + 42}{2}$

$5x + 4 = 3x + 42$

$5x - 3x = 42 - 4$

$2x = 38$

$x = 19$

$substituting \: x = 19 \: \:in \: \: \: \: \: \: \: \\ m$

We get,

m<ABC =

$(5 \times 19) + 4 = 99$

Hence <ABC is obtuse
