Need help! Law of cosines...find b round to the nearest tenth please

dusya [7]

ANSWER

$B = 27.8 \degree$

EXPLANATION

The law of cosine is given by the formula:

${b}^{2} = {a}^{2} + {c}^{2} - 2bc \cos(B)$

From the diagram,

a=17, b=8, c=16

We substitute the given values into the formula to obtain:

${8}^{2} = {17}^{2} + {16}^{2} - 2(17)(16)\cos(B)$

$64 = 289+ 256- 544\cos(B)$

$64 = 545- 544\cos(B)$

$64 - 545 = - 544\cos(B)$

$- 481 = - 544\cos(B)$

$\frac{ - 481}{ - 544} = \cos(B)$

$cos(B) = 0.88419$

$B = \cos ^{ - 1} (0.88419)$

$B = 27.8 \degree$

Solve the equation. Then check your solution. - (3a + 4) = 7 Helppp

Sati [7]

Answer:

a= $-3\frac{2}{3}$ or ≈ -3.66

Step-by-step explanation:

-(3a+4)=7

-3a-4=7

Add 4 to both sides

-3a=11

Multiply both sides by -1

3a= -11

Divide both sides by 3

a= $-3\frac{2}{3}$

15. During the summer, Briana runs an ice cream shop. Her biggest seller is waffle ice cream cones. She charges $1.85 for a waff

Ivahew [28]

15) It is given that the charge of the waffle cone = $1.85

Charge per scoop of an ice cream = $0.60

Let C be the total cost.

So, total charge of one wafflce cone ice cream = charge of the waffle cone + (0.6 times number of scoops

C = 1.85 + 0.6x

16) To find the cost for 6 scoops of ice cream, put x = 6 in the above expression and simplify.

C = 1.85 + 0.6(6)

= 1.85 + 3.6

= 5.45

Hence, cost of 6 scoops of ice cream = $5.45.
