Answer:

x = 0.2699 or 15 .47°

Step-by-step explanation:

Given  : sin x = \frac{4}{15}.

To find : find  x.

Solution : We have given that

sin x = \frac{4}{15}.

Taking inverse of sin

sin^{-1} sin x = sin^{-1}(\frac{4}{15} ).

x = sin^{-1}(\frac{4}{15} ).

x = 0.2699 or 15 .47°

Therefore, x = 0.2699  or 15 .47°

From here, just make it inverse:

sin^{-1} ( \frac{4}{15}) = x
x=15.46600995.....

Use the diagram below to match the ratios below. B a A b sin B COS B tan B tan A COS A sin A​
Paha777 [63]

Answer:

See explanation

Step-by-step explanation:

Given

The attached triangle

Required

Complete the ratios

(a) sin B

\sin(B) is calculated as:

\sin(B) = \frac{Opposite}{Hypotenuse}

\sin(B) = \frac{b}{c}

(b) cos B

\cos(B) is calculated as:

\cos(B) = \frac{Adjacent}{Hypotenuse}

\cos(B)  = \frac{a}{c}

(c) tan B

\tan(B) is calculated as:

\tan(B) = \frac{Opposite}{Adjacent}

\tan(B) = \frac{b}{a}

(d) tan A

\tan(A) is calculated as:

\tan(A)= \frac{Opposite}{Adjacent}

\tan(A) = \frac{a}{b}

(e) cos A

\cos(A) is calculated as:

\cos(A) = \frac{Adjacent}{Hypotenuse}

\cos(A) = \frac{b}{c}

(f) sin A

\ain(B) is calculated as:

\sin(B) = \frac{Opposite}{Adjacent}

\sin(B) = \frac{a}{c}

Which of the following equations could be used to solve for x in the triangle shown? tan48°=10/x
galben [10]
Acronym to remember the 3 basic trigonomic functions: 

Soh - Cah - Toa 

             opposite
sin = --------------------
            hypotenuse

              adjacent 
cos = -------------------
             hypotenuse

             opposite 
tan =  -----------------
             adjacent 


In your case, you can set up a sine trigonomic function, like this: 

Sin 48 = 10      (adjacent)
               -----  
                 x       (hypotenuse)

                       10
 (x) Sin 48 = ------ (x)
                         x

  (x) Sin 48 = 10 
 --------------   ------------- 
  Sin 48         Sin 48 

Plug in 10(sin)(48) into a calculator.

x = 7.43


I just realized that you didn't ask me to find the answer, but now you will know even more than you need to :D

The figure below shows two half-circles at the ends of a rectangle with the dimension shown.
timurjin [86]

Answer:

D. 154

Step-by-step explanation:

The area of the rectangle is 15*5= 75 inches

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633

75 + 78.53981633 is about 154
