Answer:

sin A = 3/5

cos A = 4/5

tan A = 3/4

Step-by-step explanation:

Using the trigonometric ratios;

SOH CAH TOA

Sin A = opposite/hypotenuse

cos A = adjacent/hypotenuse

tan A = opposite / adjacent

From the diagram given;

opposite = 3        adjacent =4

We can find the value of the hypotenuse by using the Pythagoras theorem

opposite²  +  adjacent² = hypotenuse²

   3²           +      4²         =hypotenuse²

             9   + 16   =hypotenuse²

            25  = hypotenuse²

take the square root of both-side

√25 = √hypotenuse²

 5   = hypotenuse

hypotenuse = 5

sin A =  opposite / hypotenuse

sin A = 3/5

cos A = adjacent/hypotenuse

cos A = 4/5

Tan A = opposite /adjacent

tan A = 3/4

Ben is 3 times as old as Daniel and is also 4 years older than Daniel.<br> How old is Daniel?
Georgia [21]
B=3d and b=d+4 

Since b=b we can say:

3d=d+4  subtract d from both sides

2d=4  divide both sides by 2

d=2

Daniel is 2 years old.  (and Ben is 6 years old)

Answer:

  • JK ≈ 6.86 units

Step-by-step explanation:

According to the diagram MK is the angle bisector of  ∠LMJ in the triangle LMJ.

Use angle bisector theorem, which states:

  • <em>an angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.</em>

<em />

Applied to the given triangle, the ratios are:

  • LK/JK = LM/JM

Use segment addition postulate and substitute known values to get:

  • (LJ - JK)/JK = LM/JM
  • (14 - JK)/JK = 50/48
  • 50JK = 48(14 - JK)
  • 50JK = 672 - 48JK
  • 50JK + 48JK = 672
  • 98JK = 672
  • JK = 672/98
  • JK = 6.86 (rounded)

Graph the function f(x)=-4/3x+4
babymother [125]

Answer: Option D is correct.

Step-by-step explanation: An exponential function is in the form of  where a is the initial value and b≠ 0 , b >1 .

Given: The function f(x) = y =            ......[1]

The domain is all real numbers and the range is y > 0.

y-intercept defined as the graph crosses the y-axis.

Substitute the value of x= 0 in [1] to solve for y;

y =   = 4

y-intercept = (0, 4)

End behavior:

when b =3 >1

then;

as  ,  

as   ,  

therefore, the only graph which represents the function y =    is Option D
