Find the value of y round your answer to the nearest tenth cos y y=8/13

Iteru [2.4K]

8/13 = 0.6153

y = cos-1(0.6153)

y = 52.0

I'm not totally sure if this is what you mean or if this is.

y = cos(8/13) = 0.9999 which to the nearest tenth is 1.0

Anne-marienhas saved 9 dollars for a new coat that is 1/6 as much money as she needs how much does the coat cost

Tatiana [17]

Answer:

Cost of the coat = $54

Step-by-step explanation:

Given:

She saved = $ 9

To Find:

Cost of the coat = ?

Solution:

Let the price of coat be x

She saved $9

and according to given condition it is 1/6 of the total money she needs for buying coat

by this we have

$\frac{1}{6}*x = 9$

Multiplying both sides by 6

$\frac{1}{6}*x*6 = 9*6$

it becomes

x = 9*6

x = $54

As x is the amount she needs

Cost of the coat = $54

Please help using law of cosines!

Tamiku [17]

Answer:

∠ A ≈ 48°

Step-by-step explanation:

Using the Cosine rule to find an angle

cosA = $\frac{b^2+c^2-a^2}{2bc}$

with a = 10, b = 13 and c = 11

cosA = $\frac{13^2+11^2-10^2}{2(13)(11)}$

= $\frac{169+121-100}{286}$

= $\frac{190}{286}$ , thus

A = $cos^{-1}$ ( $\frac{190}{286}$ ) ≈ 48° ( to the nearest degree )
