ANSWER

(C)38.16

EXPLANATION

The acute angle given in the right triangle is 27°.

The side length adjacent to the 27° angle is 34 units.

The side length we want to find is x units, which is the hypotenuse of the right triangle.

We use the cosine ratio to obtain:

\cos(27 \degree)  =  \frac{adjacent}{hypotenuse}

\cos(27 \degree)  =  \frac{34}{x}

Solve for x,

x  =  \frac{34}{\cos(27 \degree)}

x = 38.16

to the nearest hundredth.

Answer:

The correct answer is option C.  38.16

Step-by-step explanation:

<u>Points to remember</u>

<u>Trigonometric ratios</u>

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

<u>To find the value of x</u>

From the figure we can see a right angled triangle. △JKL

Cos 27 = Adjacent side/Hypotenuse

 = KL/JL

 = 34/x

x = 34 / Cos 27

 = 34 / 0.891

 = 38.16

Therefore the correct answer is option C.  38.16

At a charity fund raiser , adult tickets were sold for 8$ children each and children’s tickets were sold at 2$ each. write an algebraic expression for the total amount raised from the sale of tickets. How much money was raised if the fundraiser sold 238 adult tickets and 375 children’s tickets?

Step-by-step explanation:

2,654$

Step-by-step explanation:

8a + 2c

Mkey [24]

Answer:

Billy next to the 65 degree angle

Ray next to the 60 degree angle

Cyrus next to the 55 degree angle

if we were to put this into A squared + B squared = C squared it would be Cyrus squared + Ray squared = Billy squared  

Also lol Billy Ray Cyrus (Miley Cyrus Dad)

Explaination:

It literally says it right here "Cyrus to stand by the 55o angle, Ray by the 60o angle, and Billy by the 65o angle. Determine which vertex each boy should stand next to."

Answer:

Sculpture in the round.

After the return of the couple from a tour to Spain Picasso created the bust in Paris. As in his old Cubist pictures, the frame of her sculpted head is faceted into miniature pieces. Meant to be viewed in the round, the production switches form when seen from various corners. Therefore, it is clear that Pablo Picasso’s "Head of a Women" was a sculpture in the round.
